--- Comment #5 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- (In reply to Louis Dionne from comment #4) > Still fails on trunk. Out of curiosity Markus, do you use software to reduce > test cases? Did you generate these A, B, ... structs yourself? I normally just use https://github.com/csmith-project/creduce . But, as your testcase shows, you can sometimes reduce testcases further by hand.
