I tried the suggestion, though I had to load up some extra files to get it to work. I had to do a
LD_PRELOAD="/lib/i686/libc.so.6 /lib/i686/libm.so.6 /lib/i686/libpthread.so.0"
/lib/i686/libpthread.so.0 had to be in since /lib/tls/libpthread.so.0 would not load when /lib/i686/libc.so.6 was preloaded. I just threw /lib/i686/libm.so.6 in there to make sure I was using nothing in the /lib/tls directory if that would help things.
In the end, it crashed again. :(
Here's the links to the latest crash files.

I also tried it again, but with the same files stored in /lib instead of /lib/i686, and I got this crash:

Thanks for helping me out. Let me know what else might be an option.
Cheers,
Tim

3 of those are putenv() crashes. Whenever I see that I always think thread safety issues. In your case you are linking against the NTPL-aware libc on Redhat (/lib/tls/libc.so.6). Could you try doing this:
LD_PRELOAD=/lib/i686/libc.so.6
in your Apache startup script and let me know if it still crashes?

I need help tracking down a crash in PHP. I have not been able to work out a test case where it will crash reliably, so I have been hesitant to fill out a bug report.
Here's the kit I have running:
PHP4 - Latest Stable Snapshot as of 30/Mar/2004 12:18 Apache - 1.3.29 mod_ssl - 2.8.16 mod_perl - 1.29 Red hat 9 - 2.4.20 Kernel
The problem is when I try to access my web-mail sites, it will crash after a period of time. I have done a number of gdb sessions, but I need some help interpreting the results. You can find the gdb log from a few of the crashes here:
http://madweb.org/errors/Error1.txt http://madweb.org/errors/Error2.txt http://madweb.org/errors/Error3.txt http://madweb.org/errors/Error4.txt http://madweb.org/errors/Error5.txt
I thought it might be something to do with IMAP since the web-mail pages (IMP/HORDE and SquirrelMail), so I tried different versions of the UW IMAP client, but crashes still took place with both the 2000 and 2002 versions.
When PHP is compiled in debug mode, I got a ton of leak messages in Apache's error log.
I tried to setup a different Apache instance on a different port to use that one for debugging purposes. However, I can not get that on to crash. I have it running on ports 4080 and 4443(SSL) and I can not get it to crash even after pounding and pounding the web-mail sites.
So I have a decent amount of info to work from, not sure what to do next to get the crashes to stop. I am open to any and all suggestions to try and pin this bugger down.
