Yeah, I hit exactly this as well, with DEF_INTERNAL_FN (UBSAN_NULL, ECF_LEAF |
ECF_NOTHROW). The UBSAN_NULL is just like a macro, it expands to a GIMPLE_COND
later on. It has to be leaf - otherwise it wouldn't be possible to have it in
the middle of a BB. Temporarily, I disabled the tests with -flto.
