--- Comment #14 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > ICE still occurs with current trunk (r267728) patched with > gcc9-pr88331.patch from PR88331. r266345 seems to give quite a hard time for > cygwin / mingw targets, might be worth reverting as the gcc 9 release is > comming up. I agree, the patch is quite weird and should not have been accepted.
