--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> --- (In reply to seurer from comment #2) The warning for gcc/testsuite/gcc.dg/torture/pr57147-2.c looks correct. The g_return_jmp_buf variable has zero size but it's being passed to a function declared to take an array of one element. Let me suppress it in the test.
