--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
And -Wall says correctly

t.c: In function ‘j’:
t.c:16:14: warning: ‘m’ is used uninitialized [-Wuninitialized]
   16 |         ***o = 0;
      |         ~~~~~^~~

but we fail to diagnose that the goto crosses the initialization.  Re-opening
for that to improve.
