--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Started to ICE with r7-1710-g849a76a5a20db383. Before that it was rejected
with:

pr94762.c:4:10: error: unsafe function call ‘__atomic_compare_exchange_4’
within ‘transaction_safe’ function
   return __atomic_compare_exchange_n (&fh, &gf, 0, 0, 0, 0);
