Frankly, that sounds like an internal error in the compiler. Either
the register allocater, the temporary creator, or the register
spiller seems to be failing to do its job.
This does not appear to me to be a porting problem, but a defective
compiler. Is there any reason you must use the later compiler?

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
