EXC_BAD_ACCESS, Could not access memory zval array type

Hello, I'm trying to create an ArrayList as an extension. I'm currently implementing ArrayList::contains(mixed $element) but I'm running into a blocking issue. It's currently causing a segfault when you call contains. I've tried to track down what I'm doing wrong, but I've had no luck with it. When running gdb this is what I get: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: 13 at address: 0x00000000000000000x00000001005812ca in _zend_is_inconsistent /* {{{ proto public boolean ArrayList::contain(mixed $element[, boolean strict]) Returns true if this list contains the specified element. */ ZEND_METHOD(arraymap_class, contains) { zval *element; zend_bool strict = 0; /* strict comparison or not */ if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z|b", &element, &strict) == FAILURE) { RETURN_FALSE; } zval *this = getThis(); arraylist_object *intern; intern = (arraylist_object *) zend_object_store_get_object(this TSRMLS_CC); /* Don't use "ht" as a variable, it's already being used. All ZEND_METHOD have "ht" defined. */ HashTable *hash_table = Z_ARRVAL_P(intern->elements); HashPosition pos; zval **current; zval res; /* comparison result */ int (*is_equal_func)(zval *, zval *, zval * TSRMLS_DC) = is_equal_function; if (strict) { is_equal_func = is_identical_function; } zend_hash_internal_pointer_reset_ex(hash_table, &pos); while (zend_hash_get_current_data_ex(hash_table, (void **)&current, &pos) == SUCCESS) { is_equal_func(&res, element, *current TSRMLS_CC); if (Z_LVAL(res)) { RETURN_TRUE; } zend_hash_move_forward_ex(hash_table, &pos); } RETURN_FALSE; } I can't seem to spot any errors with this implementation. The next thing I thought that could be wrong is how I'm creating elements pointer, but that seems correct too: static zend_object_value create_arraylist_object(zend_class_entry *ce TSRMLS_DC) /* {{{ */ { zend_object_value retval; arraylist_object *intern; intern = emalloc(sizeof(arraylist_object)); intern->size = 0; zend_object_std_init(&intern->std, ce TSRMLS_CC); ALLOC_INIT_ZVAL(intern->elements); array_init(intern->elements); intern->std.ce = ce; object_properties_init(&intern->std, ce); retval.handle = zend_objects_store_put(intern, NULL, destroy_arraylist_object, NULL TSRMLS_CC); retval.handlers = &arraylist_object_handlers; return retval; } /* }}} */ I'm not getting any compilation errors or any type of warnings. Everything seems to be glueing itself correctly. I'm hoping someone can see what I'm doing wrong so that I can move forward with this. thanks!
