--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Looks like some issue with autopar outlining.
Note such cases are a recipie for GC issues since the referenced BLOCK isn't
kept live by references from locations. The BLOCK in the other function can
get removed/GCed. Those issues are hard to track down which is why we have
this verifier...
