Hello all,
I have IMagick 2.2.2 [latest stable in PECL] loaded with PHP 5.3.1. When
sending SIGHUP, Apache defuncts, the BT is as follows:

It appears to me as though IMagick's MSHUTDOWN fails to do proper
cleanup and thus, the crash occurs in the next startup but this does not
occur with PHP 5_2 [tested 5.2.12] or PHP 5.3.0 and is also resolved in
5.3.2RC1 which is good.
Can anyone refer me to the revision that solves this issue? I am asking
because I would very much like to backport it to 5.3.1.
Thanks in advance,
