Apache2 segfault

[Kövesdán Gábor]

Hello,

I have an apache 2.0.53 from the prots colletction with auth, dav, misc, 
ssl, threads modules on FreeBSD 5.3 amd64.Some of the httpd processes 
crash with SIGSEGV signal (11). Most of the web pages are reachable, but 
some aren't. (e. g. Squirrelmail) In the apache error-log I can see such 
messages:

And in the syslog:

This phenomenon has been existed since approximately I upgraded the 
apache webserver from .52. Generally I use CFLAGS=-Os -march=athlon64 
and gcc4.0. But now, I deleted the dependencies of the apache webserver, 
commented the whole make.conf out, and recompiled almost everything for 
apache and the result is the same. What can I do now? Please help me, it 
is quite important since this is a production system....
