Have you tried taking a shower? ;)

We have a different libc, though mine reports a wrong library. it reports the 
lib it was compiled with libc=/lib/libc-2.2.5.so. However

   % ldd ~/perl/5.6.1-ithread/lib/5.6.1/i686-linux-thread-multi/CORE/libperl.so
         libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

/home/stas/bios> l /lib/i686/libc.so.6
lrwxrwxrwx    1 root     root           13 Jan 24 09:23 /lib/i686/lib
c.so.6 -> libc-2.3.1.so*

so I'm running 2.3.1 and you 2.3.2 (maybe, check the real version with ldd). 
And that could make the difference.

Also, try to use an empty/minimal httpd.conf when you test this segfault
