Citing Jakub's PR94106 comment 2: "Nobody really maintains the -fgnu-tm stuff
anymore".
I didn't test it but it looks like Marek's patch from PR68122 comment 8, even
if is not a right fix, works this ICE around.

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’

return __atomic_compare_exchange_n (&fh, &gf, 0, 0, 0, 0);
