Dear all, we ICE'd in the simplification of FINDLOC when the passed ARRAY argument had an invalid declaration. The reason was a reference to array->shape which was NULL. Obvious solution: then just don't attempt to simplify. Regtested on x86_64-pc-linux-gnu and pushed to mainline as https://gcc.gnu.org/g:5976fbf9d5dd9542fcb82eebb2185886fd52d000 The PR is marked as a 10/11/12/13 regression, thus I plan to backport. Thanks, Harald
