--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I fixed this ICE in a followup patch, but it shows worse problem that some pass
did not initialize probability/count in CFG. So we should check why stack
checking does that.

We allow that since it can legally happen when -O0 always_inline is inlined to
non -O0, but perhaps I can add verifier and bookkeep this case in struct
function.
