[Bug other/35454] New: [4.3/4.4 Regression] m68k: internal compiler error: in find_reloads, at reload.c:3744

["bunk at stusta dot de" <gcc-bugzilla at gcc dot gnu dot org>]

This bug might be related to bug 32424 (why do you have a testsuite when
reports of ICEs when running it get completely ignored?), but I can't judge
whether it's really the same:
