Issue: https://github.com/php/php-src/issues/9145 Author: zqtop ### Description After the GDB and PHPDebug are enabled, the system reports the zend_object_handlers.c file based on the core information. An exception is reported: No such file or directory. The error function is as follows: ZEND_API zval *zend_std_read_dimension(zend_object *object, zval *offset, int type, zval *rv) /* {{{ */ { zend_class_entry *ce = object->ce; zval tmp_offset; if (EXPECTED(zend_class_implements_interface(ce, zend_ce_arrayaccess) != 0)) { if (offset == NULL) { /* [] construct */ ZVAL_NULL(&tmp_offset); } else { ZVAL_COPY_DEREF(&tmp_offset, offset); } GC_ADDREF(object); if (type == BP_VAR_IS) { zend_call_method_with_1_params(object, ce, NULL, "offsetexists", rv, &tmp_offset); if (UNEXPECTED(Z_ISUNDEF_P(rv))) { OBJ_RELEASE(object); zval_ptr_dtor(&tmp_offset); return NULL; } if (!i_zend_is_true(rv)) { OBJ_RELEASE(object); zval_ptr_dtor(&tmp_offset); zval_ptr_dtor(rv); return &EG(uninitialized_zval); } zval_ptr_dtor(rv); } zend_call_method_with_1_params(object, ce, NULL, "offsetget", rv, &tmp_offset); OBJ_RELEASE(object); zval_ptr_dtor(&tmp_offset); if (UNEXPECTED(Z_TYPE_P(rv) == IS_UNDEF)) { if (UNEXPECTED(!EG(exception))) { zend_throw_error(NULL, "Undefined offset for object of type %s used as array", ZSTR_VAL(ce->name)); } return NULL; } return rv; } else { zend_bad_array_access(ce); return NULL; } } The following figure shows the GDB debugging error.
