[erlang-bugs] Bug in enif_compare/2 for bignums

[Paul Davis]

Hello,

I think I've uncovered a bug in enif_compare/2 for bignums. Converting
the same arguments to ErlNifSInt64 values and using C comparison
returns the correct result when enif_compare does not. There's a
reduced test case at [1]. If there's nothing obvious I'll spend some
time later digging into Erlang to see if I can spot the bug.


Thanks,
Paul Davis
