When read_property fails, it may return `&EG(uninitialized_zval)`, and the exception is handled in the VM. The VM will try to `zval_ptr_dtor_nogc` the result, but the result was never set, resulting in dtor'ing garbage data. To solve this, we check when a different zval* was returned and initialize the result with UNDEF. We don't need to copy as the slow_ex handler return values are used directly in a register. Closes GH-17749. |
