I certainly can't reproduce this on x86_64-linux (with neither -m32 nor -m64).
Can you please attach the good and bad char_cshift_2.s, and the from the
debugger
which field of the array caused the abort and maybe even good and bad
char_cshift_2.*.fwprop* dumps? Can you hit breakpoint on
_gfortran_cshift1_4_char and _gfortran_cshift1_8_char and compare the incoming
and outgoing arrays between a good and bad version?
I will try to cross-compile this, but as I have no idea what to look for, it
might be a challenge.
