It seems that it's exactly the same bug as #900. The script stops with this backtrace :

This GDB was configured as "i386-unknown-freebsd"...
(gdb) run -X
Starting program: /usr/local/sbin/apache -X

Program received signal SIGSEGV, Segmentation fault.

I've a script to reproduce this problem. It's too long to be included here but i can send it to anyone interested.

PHP : 3.0.12
Apache : 1.3.9
MySQL : 3.22.25 (the MySQL server is on a Linux box).
