It could be either -- if QEMU segvs or the guest segvs the
effect will be the same. The only way to tell is to debug...
(Even if it is a guest segv, it could be caused by an earlier
QEMU bug which results in the guest going off the rails until
it eventually segfaluts.)

A useful first check is "does the binary and command line
which crashes under QEMU run OK on the real arm/mips/etc hardware?".
