New Comment:
W00ps, sorry 'bout the backtraces, thought it might help.
The configure line is pretty big, and I doubt it's of help since I
found that the change in php_fopen_wrapper.c is causing all the
trouble... (with PHP4CVS for sure).
In every bt I've seen, php_fopen_wrapper.c failed on line 81, combined
with MySQL. Often I also see a 'No such file or directory' message:
at
/opt/install/apache-2.0.54_apache-1.3.34_php-4.4.2-RC2-dev-WideXS-02_php-5.0.5/php-4.4.2/ext/standard/php_fopen_wrapper.c:81

I downloaded revision 1.29.2.4 of this file, and the segmentation
faults are now gone with PHP4CVS and Apache 2.0.54
Hopefully this is enough info for you :)

Do NOT add such long backtraces here before asked to!!
Another thing: you didn't tell what your configure line was.
Are you sure you don't have PHP 4 and 5 loaded the same time in your
httpd.conf? (assuming you're compiling them as DSOs)

Correction, PHP 5.1.0 latest (PHP 5.1.0RC7-dev) also suffers from
segfaulting...

Description:
------------
Despite the fixes of bug #35264 and #35278, I now still see a few
Apache2 child processes segfaulting in error_log, with PHP4CVS (+snap
2005-11-21)
PHP5-latest seems not affected...
I finally was able to make a backtrace this time, but the problem is
that I wasn't able to find the PHP-code that is causing these crashes.
Also, this is with Apache 2.0.54.
When upgrading machines to 2.0.55 that don't show problems with 2.0.54
now, I get segfaulting child processes on them too.
The backtrace points to php_fopen_wrapper.c:81
which is also modified 3 days ago in CVS...
And always shows a MySQL header. (either 4.1.7 or 5.0.15)
[Also, I haven't been able to get a segfault with running 'httpd -X', I
only see 'Program received signal SIGPIPE, Broken pipe.' then (despite
.gdbinit: handle SIGPIPE nostop)]
However, here the backtrace for PHP4CVS (-RC2-dev/200511211410) :
