Description:
------------
Those extensions work independently, but if loaded both often segfault happened or just decode delegate not found.

Please refer to https://bugzilla.redhat.com/show_bug.cgi?id=559675 for details.

Reproduce code:
---------------
php -n -d extension=gmagick.so  -i => ok, no error
php -n -d extension=imagick.so  -i => ok, no error

php -n -d extension=gmagick.so -d extension=imagick.so -i => segfault

Expected result:
----------------
No error, phpinfo data.
