--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
With r12-3221-g1313111fdec0d0de4228b5e839ca728b3e4b106e this started to ICE:
pr105214.c: In function ‘foo’:
pr105214.c:5:1: error: dead statement in EH table
    5 | foo (void)
      | ^~~
# _7 = VDEF <.MEM_5>
_8 = __builtin_alloca_with_align (6400, 32);
during GIMPLE pass: asan
pr105214.c:5:1: internal compiler error: verify_gimple failed
0x13781be verify_gimple_in_cfg(function*, bool)
        ../../gcc/tree-cfg.c:5531
0x11bebdf execute_function_todo
        ../../gcc/passes.c:2042
0x11bdb7b do_per_function
        ../../gcc/passes.c:1687
0x11bedcf execute_todo
        ../../gcc/passes.c:2096
and with r12-7214-gf0c7367b8802c47efaad87b1f2126fe6350d8b47
that turned into the connect_traces ICE.
