Ehum. That failure was apparently due to a qemu bug. Sorry.
I tested qemu 4.2.0 and qemu 5.2.0. The latter does not work at all,
not even for "ls" or "cat". The former runs submul_1 for a while, but
ultimately reports an error. The error is not reproducible.
This is on a server system with ECC. It is either some problems in your
submul_1, e.g. incorrect handling of callee-saves registers, or an
uninitialised register or flag, or a bug in qemu.
I cannot provoke any similar problems with your addmul_1.
