--- Comment #43 from Avraham Adler <avraham.adler at gmail dot com> --- 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?
