PHP crashes frequently (document contains no data in netscape and segmentation fault (11) in error_log). If I try to run the same script again, it usually sucseeds. Script contains no syntax errors.

PHP configure line:
./configure --with-mysql --with-apxs --disable-debug --enable-track-vars --with-gd=/usr

Apache 1.3.12-2 was installed from rh6.2 cd.

php.ini contains these lines:

Zend optimizer is RC1-Linux-glibc2.1

(no debugging symbols found)...
(gdb) run -X
Starting program: /usr/sbin/httpd -X

Program received signal SIGSEGV, Segmentation fault.
