--- Comment #3 from Alex Coplan <acoplan at gcc dot gnu.org> ---
@Martin: I originally saw the issue with a testcase generated by YARPGen
(https://github.com/intel/yarpgen), but this only hit the bug with LTO.

I reduced that with cvise and then manually tweaked the testcase to simplify it
such that it also hits the bug without LTO.
