segfauls with ZEND_FETCH_RESOURCE (my first php extension...)

Hi I wrote today my first php-extension and so far, everything worked fine, until i used ZEND_FETCH_RESOURCE. My module seems not to be able to handle that well, 'cause if i use it like the other extensions, i get a segfault. The offending line is: ZEND_FETCH_RESOURCE(test, php_test*, arg1, -1, "magick object", le_magick); which produces the following segfault (from gdb): Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 1024 (LWP 7524)] 0x40224fa9 in zend_fetch_resource (passed_id=0x8123634, default_id=-1, resource_type_name=0x4037a630 "magick object", found_resource_type=0x0, num_resource_types=1) at zend_list.c:123 123 } else if ((*passed_id)->type != IS_RESOURCE) { If i change the -1 to 1, then it handles Resource ID #1 without any problem, but that's certainly not the solution, since everyone else uses the -1.... I stripped my code down until it does not much useful, only the ressource stuff, but i still get segfaults. The code is accesible at http://cvs.bitflux.ch/index.cgi/pearlib/magick/ any help/hints/etc is/are very welcome. I'm sure it's something very stupid.
