Operating system: CentOS 5.3
PHP version: 5.2.10
PHP Bug Type: Reproducible crash
Bug description: Opening error_log causes segfault
Description:
------------
With 5.2.10 I am receiving a segfault whenever the error_log file is
opened. If recompiled on the same server with php 5.2.9, it completes with
an successful entry in the error_log. If the facility is changed to syslog
in 5.2.10, it completes successfully with an entry sent to syslog.
Reproduce code:
---------------
Any error causing entry in php.ini will trigger the segfault. IE,
"extension=bogus.so". php -v will cause a segfault with that in the ini
file.
Expected result:
----------------
An entry successfully appended to ./error_log stating the error.
Actual result:
--------------
strace of php -v with "extension=bogus.so" in ./php.ini
