Operating system: FreeBSD 6.2
PHP version: 5.3CVS-2009-04-01 (CVS)
PHP Bug Type: Arrays related
Bug description: array() returns NULL
Description:
------------
Again, another bug happening in a unit test of OpenX. The problem always
happens in the same test at the same point. What happens is that a simple
array() call is returning NULL on my FreeBSD system. The same test
generates a segmentation fault when run on our Linux based continuous
integration system.
Unfortunately I can't create a self-contained test case, but I can provide
access to the system or more data.
I will also attach a backtrace of the core dump (which might even not be
happening at the same place as the FreeBSD failure).
Reproduce code:
---------------
$ids = array();
echo 'On FreeBSD: ';
var_dump($ids);
Expected result:
----------------
On FreeBSD: Array ()
Actual result:
--------------
On FreeBSD: NULL
Backtrace (Linux):
Program terminated with signal 11, Segmentation fault.
