I'm having a little problem. I have a dial-plan with a lot of SetVar's and loops, and under certain circumstances (reproducible) it makes asterisk crash. Wanting to debug this, I compiled using "make valgrind". But doing so, I eliminated the crashes and the dial-plan works perfectly. Now from what I understand, valgrind removes compiler optimisation to ease debugging. What kind

I've got a friend who's spending 6 months on the other side of the world. So before he left I configured him a softphone on his laptop to connect to my asterisk so he can call home free of charge. Unfortunately, he just found out he has horrible internet connection. Bandwith and latency is ok, the problem is the stop almost all connections. He has to connect to a proxy server for his web

Hello all, I've been playing around with early audio, and I'm able to get some things working We have PSTN calls coming in to asterisk in SIP from a Cisco AS5300. If I do the following: Exten => i,1,Playback(ss-noservice,noanswer) Exten => i,2,Congestion(15) Exten => i,3,Hangup() The PSTN caller does not get an answered call (doesn't get billed) but hears the ss-noservice

R CMD check --use-valgrind <packagename> used to run valgrind on the tests in the tests directory of the package. But it seems to have stopped. R-2.9.1 doesn't -- at least on my box -- and neither does R-2.10.0 (devel). I am not sure when this stopped. I think 2.8.x did this. The only old R I have around is 2.6.0 and it certainly does. R CMD check --help for 2.9.1 says (among other

When we are valgrinding we don't really care about the child processes, which might be qemu, libvirtd, etc. So disable tracing into children (at least, as far as is possible with valgrind, which is not entirely disabling it, but suppressing it). --- m4/guestfs_progs.m4 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/m4/guestfs_progs.m4 b/m4/guestfs_progs.m4 index

I am trying to do a classic R -d valgrind --vanilla < mypkg-Ex.R as described in http://cs.swan.ac.uk/~csoliver/ok-sat-library/internet_html/doc/doc/R/2.9.1/doc/manual/R-exts.html#Using-valgrind The problem is valgrind crashes imediately. I am using Ubuntu 10.04 LST (actually Biolinux) on a 64bit Dell Precision laptop with 4 core-i5 Intel processors. I have R-2-15-0 installed from source

From: "Richard W.M. Jones" <rjones at redhat.com> This commit allows you to run the daemon under valgrind. You have to enable it at configure time: ./configure --enable-valgrind-daemon This should *not* be done for production builds. When this feature is enabled, valgrind is added to the appliance and the daemon is run under valgrind. Log messages from valgrind are passed

Full_Name: Martin Schlather Version: 2.10.0 OS: linux Submission from: (NULL) (91.3.220.231) Bug summary: some functions behave differently for NAs when valgrind is used in R, e.g. sum and prod Bug demonstration: --- without valgrind ---- > sum(c(NA,1)[1]) [1] NA --- with valgrind ---- > sum(c(NA,1)[1]) [1] NaN R call with valgrind: R -d "valgrind --tool=memcheck

Instead of forcing valgrind to be run when --enable-valgrind-daemon is passed to configure, enable it only when the backend setting "valgrind_daemon" is set. This allows developers to keep building with --enable-valgrind-daemon, which unconditionally adds valgrind in the appliance but using only when requested. When --enable-valgrind-daemon is not passed (typical for release builds),

"R Installation and Administration", section 2.5 "Sub-architectures" describes calling specific builds of R using the call "R --arch=name". I am trying to build and install three versions of R-2.9.1, each configured with a different valgrind-instrumentation level ("Writing R Extensions", section 4.3.2 "Using valgrind"). My goal is to be able to

Dear R developers I am running an instrumented build of R 2.6.1 on ubuntu, compiled with option configure --with-valgrind-instrumentation=3. If run valgrind R then I get all sorts of warnings. I was wondering whether I should worry about them or not. First, when I open R as follows: $R -d "valgrind --tool=memcheck --leak-check=full --show-reachable=yes" --vanilla I get a whole

Hi, I just pushed valgrind support for the regression and unit tests. If you run "make tests USE_VALGRIND=1" then almost all the tests will be run under valgrind. The valgrind output is dumped in regress/valgrind-out with a file per { test, binary, PID }. There is no analysis or summarisation yet (want to help? write a summarisation script) Some warnings: First, it's slow. My

Hi, only one letter got to valgrind-developers mailing list. I'll quote the first message of the thread so that those who do not read llvmdev knew what's this discusssion about. === Begin of the first message === > Hi, > > I've seen on the LLVM's Open Projet Page [1] an idea about using LLVM to > generate native code in Valgrind. For what I know, Valgrind uses libVEX

Hi, I am trying to integrate valgrind with sftp-server. I've replaced the sftp subsystem line in /etc/ssh/sshd_config file as follows: Subsystem sftp /usr/bin/valgrind --log-file=~/abc --trace-children=yes /root/openssh-6.2p2/sftp-server But I am not able to connect to the sftp-server. These are the last messages that the client logs. <snip> debug1: Sending subsystem: sftp

Hi: I have been working on Valgrind [porting it to non-supported architectures] and wanted to know what you guys think of Valgrind for LLVM. I haven't thought through fully myself - so wanted to get your inputs before becoming rigid in my own opinion. Original Valgrind works on object code - translating the asm to its own IR [intermediate representation]. But for LLVM, probably putting the

Hi, Just a thought... How are you going to port llvm so it doesn't use libc? Valgrind uses the same resources as the running program, so it can't use the system libc's malloc nor any other functions so it doesn't get "confused".

But I can't think of a reason that valgrind needs executable data segment. It is likely that valgrind assumes some specific segment layout that the GNU linker creates and can't handle other layout even if it is valid.
