[PHP-DEV] PHP 4.0 Bug #6873: SIGSEGV on SEPARATE_ZVAL_IF_NOT_REF From: alex <email protected>
Date: 09/24/00

From: alex <email protected>
Operating system: linux-glibc21
PHP version: 4.0.2
PHP Bug Type: Scripting Engine problem
Bug description: SIGSEGV on SEPARATE_ZVAL_IF_NOT_REF

I can not send the PHP script that reproduces the core dump because it is
too large.

Below is the backtrace of the problem. It occurs with the CGI and the APACHE DSO SAPIs. The PHP stops coredumping when the ZendOptimizer is activated.

Program received signal SIGSEGV, Segmentation fault.
