similar to: R valgrind question

Hello, KWD crashes almost regularly when trying to start OpenOffice.org. I've attached two output files from valgrind to this e-mail (as suggested by David Reveman in another mail 11.7): Use something like: valgrind --tool=memcheck kde-window-decorator .... I'm using Trevino's git version of Compiz in up-to-date Kubuntu Feisty system. Compiz version is

Hi, I am sorry if this is perceived as a C++ question rather than an R question. After uploading an R library to CRAN (MCMCglmm) the C++ code failed to pass the memory checks. The errors come in pairs like: Mismatched free() / delete / delete [] at 0x4A077E6: free (vg_replace_malloc.c:446) by 0x144FA28E: MCMCglmm (MCMCglmm.cc:2184) Address 0x129850c0 is 0 bytes inside a block of size 4

Can you try with valgrind? It will slow down the logins a bit though.

The following code crashes after about 300 iterations on my?x86_64-w64-mingw32?machine on R 3.5.2 --vanilla.?? Others have duplicated this (see?https://github.com/tidyverse/magrittr/issues/190?if necessary), but I don't know how machine/OS-dependent it may be.?? If it doesn't crash for you, please try increasing the length of the x vector. Substituting the commented-out line for the one

Hi, and thank to you all for this great codec ! I have this bug on Debian Lenny with compiled packages of last svn versions of ffmpeg and libtheora. This seems to append only on the amd64 arch. Here is a valgrind log : pre-barreau at augustins:~/video$ export LD_LIBRARY_PATH=/usr/local/lib pre-barreau at augustins:~/video$ valgrind /home/pub/apps/ffmpeg_dev/ffmpeg_svn/ffmpeg -i

Hi, I compressed a folder with the following script: ... for i in *.*.*; do file $i | grep bzip2 >/dev/null 2>&1 if [ $? -ne 0 ]; then echo "Compress: $i" cat "$i" | bzip2 -9 > ../tmp/$i if [ $? -eq 0 ]; then mv ../tmp/$i $i fi else

I have ran under valgrind memcheck the process using libLLVM-2.9.so (rev.126022) and got several errors: ==24227== Invalid read of size 1 ==24227== at 0x40274C9: memcpy (mc_replace_strmem.c:497) ==24227== by 0x40D5B84: char* std::string::_S_construct<char const*>(char const*, char const*, std::allocator<char> const&, std::forward_iterator_tag) (in

Hello Duncan, Thank you for your quick answer. I use the standard Makefile from a pass, that is calling Makefile.common. I saw only the make -d option, that "*print lots of debugging information*", as mentioned by LLVM. Using this, valgrind don't tell me extra info. It is a very good idea ti use -g, but where to insert? If I am trying to use clang++, I have to fix a lot of things.

Hi Samba developer people, I still have a problem were winbindd panics every time I run it. I'd hoped this might get fixed as newer releases of Samba came out, but I'm now running 3.0.2pre1 and still the same problem. I want to deploy Samba on Solaris, but was unable to successfully get samba to compile with dmalloc support, so I've had to install onto RedHat 8 and use valgrind

Hello Does anybody happen to know if it is possible to use the survey package to estimate a covariance matrix from a complex survey? I have design weights and clusters (no strata), and want to get a covariance matrix with preferably the effective sample size or else an estimate of the variance-covariance matrix of the covariance matrix ("asymptotic covariance matrix"). Is this

Hi Alexandru, if these are LLVM Makefiles, then I suggest you configure and build LLVM with the options: --disable-optimized --enable-assertions This will make debugging much easier. It enables debug info too, which you can also turn on directly by configuring with --enable-debug-symbols. Ciao, Duncan.

I think there is a memory bug in `substr` that is triggered by a UTF-8 corner case: an incomplete UTF-8 byte sequence at the end of a string.? With a valgrind level 2 instrumented build of R-devel I get: > string <- "abc\xEE"??? # \xEE indicates the start of a 3 byte UTF-8 sequence > Encoding(string) <- "UTF-8" > substr(string, 1, 10) ==15375== Invalid read of

Attached is a patch that adds 5 missing FLAC__metadata_object_vorbiscomment_* functions to the VorbisComment class. In my previous message I stated 8 functions were missing, but on closer inspection, 3 of those belong in the VorbisComment::Entry class, and 2 of them already have equivalent functions in there. The last one (FLAC__metadata_object_vorbiscomment_entry_matches()) does not, but I have

Dear all, I am trying to install R on a (Linux Debian) machine where I do not have root access. So far I succeeded in compiling from source and running R. But I would really like to be able to use "make install" and to be able to install certain packages such as foreign. Now these actions require permissions for directories that I do not have. In particular I would like R home to be

Hi all, I'm preparing a package which uses .Fortran to interface a Fortran 95 function. This F95 function simply receives the name of a file from R, opens this file and forwards its content to a F95 module, which, in turn, makes the real computation. The F95 module is a pre-existing one and I'm trying to use it in its actual state. Thus, data transfer between R and this F95 module is
