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
