--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Martin Liška from comment #2) > Confirmed, the df-scan ICE appeared in r239383 and the folding stuff > disappeared in r233852. Ok, problem with 5 branch is that r233852 was wrongly back-ported (r234773), the hunk in fold-const.c is not applied. Applying the hunk, ICE has gone for GCC 5 branch. I'm going to test it once more and send to ML.
