I am not using the RedHat supplied apache/php rpms but compile them

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

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

[forkscrabble forum]% gcc -v
Reading specs from
gcc version 2.95.3 20010315 (release)

and then I compiled it with Sun Workshop cc and got the same results as
if it was compiled with gcc.

Which compiler did you use? What version?
