New Comment:
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
Running php on test.php:
[EMAIL PROTECTED] php4-STABLE-200307151730]# sapi/cli/php -n test.php

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

Can you please try this configure line with fresh snapshot:
# ./configure --disable-all --disable-cgi --enable-session
And run the test script like this:
# sapi/cli/php -n test.php
Does it still crash..?
