similar to: Seg Fault memory violation

Hi all, I'm not sure if I'm not supposed to do the following (the dyn.unload part, I mean) or this could be a bug (in R or Rcpp): ``` Rcpp::sourceCpp(code=' #include <Rcpp.h> class Object {}; //[[Rcpp::export]] SEXP new_object() { return Rcpp::XPtr<Object>(new Object()); }' ) new_object() dyn.unload(list.files(tempdir(), ".(so|dll)$",

R's dyn.unload() will unconditionally unload the given shared object; it does not check whether there is any object (external pointer or weak reference) with a C finalizer pointing into the space of the shared object being unloaded. So it is expected that R will segfault later when such finalizer is run. Currently there is no other way than to handle this on the side of the shared

That would be because the product nc * ni overflows in cbuf = buf = CallocCharBuf(nc * ni); Since we disallow strings with more than 2^31-1 bytes we could test and reject this. It might be more future-proof to change the declaration of int j, ni, nc; to R_xlen_t j, ni, nc; and let the character allocation code reject, but that would create a memory leak since the Free call

We've had this more general topic on R-help, and also in R-devel recently. There's one case here where I get the feeling R never gets into swapping but more directly aborts possibly from a bug we can more easily fix. Today I've been working (successfully! - not yet committed) at fixing str() for very large strings. In this process, I've found that pc <- function(.)

Hi Consider the following example: f <- function(expr) g(expr) g <- function(expr) { ? h(expr) } h <- function(expr) { ? expr # evaluation happens here ? i(expr) } i <- function(expr) { ? expr # already evaluated, no costs here ? invisible() } rprof <- tempfile() Rprof(rprof) f(replicate(1e2, sample.int(1e4))) Rprof(NULL) cat(readLines(rprof), sep = "\n") #>

Hi all, I'm unable to put app_festival to work. I successfully patched, installed and tested festival (interactive logon and telnet to server port) which seems to work without problems. But when I test it in asterisk I got the following trace in console: -- Executing Answer("SIP/bsenicar-850b", "") in new stack -- Executing

I ran into an interesting issue with `evalq` (and also `eval(quote(...))`): ???? f <- function() { ?????? list( ???????? sys.parent(1), ???????? evalq(sys.parent(1)), ???????? evalq((function() sys.parent(2))()),? # add an anon fun layer ???????? evalq((function() sys.parent(1))()) ?????? ) ???? } ???? res <- f() ???? str(res) ???? ## List of 4 ???? ##? $ : int 0???????? # sys.parent(1)

I am using Festival to synthesize some menu Interaction with a caller and am having a problem. What I am working on is a remote callback where I can remotely call in to an extension, and enter a callback number (or use the CALLERID info) and a second outbound dialing number to connect to. Things work O.K. until I set usecache=yes in festival.conf. After doing this, things run well for

In an optimized build, debug info is just an approximation. It might help to debug in a build of R and packages without compiler optimizations (-O0), where the debug information is accurate. However, first I would try to modify the example to trigger more often, or try to find external ways to make it trigger more often (e.g. via gctorture). Then I would try to make the example smaller (not

A reply from stackoverflow suggests I might have hit this bug: https://sourceware.org/bugzilla/show_bug.cgi?id=14023 I can confirm that this glibc bug affects my system (latest CentOS 7). However, as far as I know, R is not multithreaded in its core. Is it possible that some library triggered this? Regards, Steve Tomas Kalibera <tomas.kalibera at gmail.com> ?2019?8?2??? ??4:59??? >

Hi , I tried to do the following . Before I execute the R script , i tried to clear the work space using rm(list = ls(all = TRUE)); . I get the following back trace . Its a huge backtrace , attached a part of it . Can anyone help why I get this ? #13 0x00002aaaaafd612f in Rf_eval (e=0x1448d68, rho=0x16c6780) at eval.c:399 #14 0x00002aaaaafdabf6 in Rf_applyClosure (call=0x1447108, op=0x1448f60,

Interestingly enough I had this same problem today.... 1. I created the directory and permissions for the directory " /var/lib/asterisk/festivalcache/ " (per the comment in the festival.conf file) 2. I had to comment out some things in the festival.conf file: the "host" line, the "port" line, and the "festivalcommand" line. I have also noticed the

Earlier this afternoon I had this working exten => 2890,1,Answer exten => 2890,2,GoTo(12) exten => 2890,12,Wait(1) exten => 2890,13,Festival('I can say numbers like') exten => 2890,14,SayNumber(1230001,f) exten => 2890,15,Wait(1) exten => 2890,16,HangUp I was so very proud of myself... All of a sudden after a reboot.... I get the following from the same call plan

The R script I run daily for hours looks like this: while (!finish) { Sys.sleep(0.1) time = as.integer(format(Sys.time(), "%H%M")) # always crash here if (new.data.timestamp() <= time) next # ... do some jobs for about 2 minutes ... gc() } Basically it waits for new data, which comes in every 10 minutes, and do some jobs, then gc(), then loop again. It

Asterisk v1.0 is running on RH 9. I installed festival RPM (festival-1.4.2-16.i386.rpm) and edited the festival.scm file to add: (define (tts_textasterisk string mode) "(tts_textasterisk STRING MODE) Apply tts to STRING. This function is specifically designed for use in server mode so a single function call may synthesize the string. This function name may be added to the server safe

Hello, (This is follow up from this thread: http://www.nabble.com/execution-time-of-.packages-td22304833.html but with a different focus) I am often confused by the result of the profiler, when a loop is involved. Consider these two scripts: script1: Rprof( ) x <- numeric( ) for( i in 1:10000){ x <- c( x, rnorm(10) ) } Rprof( NULL ) print( summaryRprof( ) ) script2:

*Summary: * During package loading the library function calls file.info to determine if a file is a directory. This uselessly invokes getpwuid and getgrgid which can be expensive if the user/group database are held on a network. Note that file_test ALSO uses file.info for the same purpose Suggest rebuilding file_test to use ‘stat’ based call for directory search, and using file_test in

Hi All! I am working on a complete migration from an old solaris machine running Cyrus IMAP v2.3.14 and wish to migrate all users to a new ubuntu vm running Dovecot 2.0.19. What I have so far is a fully functional dovecot installation with LDAP / Dovecot SASL auth using Maildir++. My plan is to use Perdition IMAP proxy on a third host and migrate users a few at a time (see attached picture of
