It sounds like the program had an instruction that QEMU doesn't
recognise, or doesn't think should be allowed on the current CPU which
you've set with -cpu. You might be able to find out what that
instruction is by putting this on your qemu command line:
-singlestep -d in_asm
that will cause it to only translate one instruction at a time, and to
dump each one as it is translated. The last one printed will very likely
to be the one that is causing the problem.
Cheers
