Everytime I call zend_hash_str_find_ptr to a HashTable which is initialized in PHP_GINIT_FUNCTION, it crashes with segfault. If I move initialization of HashTable into PHP_RINIT_FUNCTION, it worked. Also, if I use malloc instead of ALLOC_HASHTABLE, it worked, too. And also, if I set USE_ZEND_ALLOC=0, it worked, too. It looks like a bug related GC but I can't pretty sure. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77510&edit=1
