--- Comment #4 from Thomas Neumann <tneumann at users dot sourceforge.net> --- I am not sure what caused that, but in GCC 13 the unwinding logic now looks into the table when registering the frame, while previously the table was only inspected on the first exception. Which means we might notice invalid tables earlier.
