PHP Bug Type: PDO related
Bug description: PDO Segmentation Faults ...
Description:
------------
hi,
as i have fairly limited server-related and C knowledge, i'm not quite
sure what is going wrong with my app via the backtrace - however it does
seem as though it's a PDO/MySQL issue.
only certain pages on my app are crashing, not all of them - however, it
seems that apache is logging a segfault anyway, whetehr this page is
displayed or not. i'm using prepared statements and bindParam with PDO, if
that's of any extra help ...
here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.

Reproduce code:
---------------
part of a big framework, so can't really post a script here - and also the
URL is part of an admin interface, which i obviously can't paste access to
here.
Actual result:
