--- Comment #7 from Rainer Orth  ---
While my original testcase fails on gcc 7, 8, and 9, the one reduced using gcc
9
only failed on trunk.  I've now ran creduce with the original testcase against
both gcc 7 and 8.  Each run produced a different reduced testcase, neither of
which is fixed by applying the trunk patch to the branches.

At least on x86_64-linux on the testcase in the patch this started to ICE with
r265677, so it is a recent regression.
