--- Comment #44 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Thank you, Dmitry, but that particular solution may not be possible for me. > When I try compiling with -mstackrealign -mpreferred-stack-boundary=5 > -mincoming-stack-boundary=5 instead of forcing unaligned moves I get > "cc1.exe: error: '-mpreferred-stack-boundary=5' is not between 3 and 4". Is > that this bug in a different form, something that should be filed > separately, or known and intended behavior? No, it's the same issue: 32-byte stack alignment is not supported with SEH.
