Interestingly, I am getting the same (similar?) bug on a Linux system
(RedHat 7.3) with apache 1.3 and php 4.3.2. My stack trace from gdb:

I did the following configure line with fresh snapshot with debug
enabled. Hopefully, this will pinpoint the problem even better.
./configure --disable-all --disable-cgi --enable-debug
--enable-session

I've also tried GCC 3.2 on Sun Solaris 5.8 and got the same results.
