Hi Geert,

Thanks for that info, I didn't know about that Amiga port.
I've looked into that implementation and it's similar to what I've done.
But as far as I can tell the code is also incomplete (the trap_c
function doesn't distinguish who caused the trap because
pt_regs->format and pt_regs->vector are pointing to some random

Is the Amiga development active? I can see that the last commit was
about 1 year ago.

Thanks and regards,
Luis Alves
