I don't have those options :) and the stack-alignment options I have make no
difference - but I think you might on the right track.  I'll investigate
whether
this is just a sign of CRIS suffering from lack of
TARGET_BUILTIN_SETJMP_FRAME_VALUE.

Can't be a dup though, same target bug but different targets.
Fixing one won't fix the other. :)  Right, changing component to target.

Thanks!
