I'm trying to run purify on CentOS on an Intel Pentium 4/630 processor. Purify does not like the 64bit code. Is there some way to compile and run programs so that they are only using the 32 bit model? I tried gcc -m32 but then the system libraries come up missing. Purify engine: Error: Couldn't open the file crt1.o...

Boy am I a dummy. I want to simply dump out unfreed allocations when I terminate the script. What''s the secret sauce? #!/usr/sbin/dtrace -s pid$1::MyAlloc:return { bufs[arg1] = walltimestamp; } pid$1::MyFree:entry /bufs[arg0]/ { bufs[arg0] = 0; } This message posted from opensolaris.org

This email isn't really LLVM specific, but is definately useful for LLVM people so.... I've downloaded and installed "valgrind" (http://developer.kde.org/~sewardj/), an open source "purify" replacement. It is actually quite a bit nicer than purify is, as it doesn't require you to recompile or modify your executables _at all_ to run them (it also seems quite fast). Anyway, if you suspect you have memory error issues, I'd recommend trying it out. It only works on x86 pl...

Hi everyone, I found that Clang -O0 performs optimizations that undermine dynamic bug-finding tools. First, most bug finding tools such as ASan, Valgrind, Dr. Memory, Mudflap, Purify and Safe Sulong (on which I am working) rely on detecting errors during the execution of the program. They either insert additional checks during compile-time or during run-time which are executed when the program is running. To find errors with these tools, it is necessary that these errors stay i...

...r example file_scanner_p->num_share_mode_entries comes back as 1651272501, which, if I understand the code, is a bit large. It looks as if the code is accessing memory it's not supposed to be accessing. Well, it looks like a memory error. I'd been meaning to try out the new version of Purify anyway, so I guess I'll go ahead and download it. Feel free to jump in with comments or questions Best regards Arnold Here's the offending routine: /******************************************************************* call the specified function on each entry under management by the shar...

SIGHUP achieves that samba checks if configuration file(s) has changed and therefore services must be reloaded (function process.c:check_reload()). Because it is touched right before, samba always decides to reload services b...

Hello, I am aware this may be an obscure problem difficult to advice about, but just in case... I am calling a C function from R on an iMac (almost shining: bought by my institution this year) and gives a "memory not mapped" error. Nevertheless, exactly the same code runs without problem in a powerful computer using SuSE Linux, but also on my laptop of 2007, 32 bits, 2 GB RAM, running

I have been working on a game for a while now and noticed that using your library to stream music created a graphical problem while the screen would scroll. (certain tiles would flicker to be more specific). I found that if I don't play music this problem doesn't occur. Another developer suggested that if I can lower the priority (thread priority) of the music this could fix the problem.

Having just spent a day trying to recover a deleted ext3 file for a friend, I'm wondering about this way of maintining undelete information in ext3, like is done for ext2: The last step in the deletion process would be to put back the (previously zeroed) block pointers. Since it gets logged to the journal, I _think_ that this should be safe. The worst that would happen is that, if the plug

(Sorry for the cross-post--- I wasn't sure which list is more appropriate...) Hi everyone, I've run into segfaults when using my randomForest package on large dataset (e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and mtry=3000). I'm wondering if anyone can give me some hints on where to look for the problem. The randomForest package mainly consists of two things:
