Subject: cure

Date: Wed, 15 Feb 2012 01:22:07 +0400

[Message part 1 (text/plain, inline)]

In PHP Imagick this problem can be cured by setting the number of used
threads to 1:

$img->setResourceLimit(6, 1); // 6 means THREAD_LIMIT (unfortunately,
there is no
such constant defined, so u have to use this integer value);

I have rebuilded imagemagick with gcc4.7 and it does not change anything.

Moreover running this program under valgrind does not segfault

Hi,

I have upgraded my package (first message was too fast) and it seems
that upgrade solve this problem. Feel free to reopen if it is does not
work on your side
