I don't understand why this patch would fix the problem, and it's
definitely not correct in general.  At least MACH_REG must remain
fixed if the target happens to be SH1, per comments right before
FIXED_REGISTERS in sh.h.

I suspect your patch is just papering over a different problem, that
could still trigger with different testcases.
