[imp] Apache Random Segmentation Faults with IMP

[Sheeri Kritzer]

OK, so we had this very same problem, but we fixed it.  (as a side note, there was a lot of stuff about "date('r')" in the archives, but nothing seemed relevant to me.).

Basically, we had the following bug in PHP (compiled with mm):

http://bugs.php.net/bug.php?id=18647

and fixed it by doing the following patch:

hope this helps people.  It helped us, we're no longer dumping apache cores.
