Operating system: IRIX 6.5.18m
PHP version:      5.0.5
PHP Bug Type:     DOM XML related
Bug description:  apache module core dumps when DOM method loadXML is called

Description:
------------
php child process core dumps while trying to execute
DOMDocument->loadXML() from within apache2

 

 

Reproduce code:
---------------
$doc = new DOMDocument();
$doc->formatOutput = true;
$doc->preserveWhiteSpace = false;

// Calling loadXML here causes the core dump
$doc->loadXML( "<hello></hello>");




Expected result:
----------------
Not to core dump!

Actual result:
--------------
It crashes.

Other possibly relevant things: The compilation of php and apache used the
native mips-pro compiler (rather than gcc).

Here's some data about the system, and the php shared object

We configured with 

./configure --with-apxs2=/local/cole/apache2/bin/apxs
--prefix=/local/cole/php-5.0.5

From the server log
[Thu Nov 03 16:16:08 2005] [notice] child pid 1749448 exit signal
