Not really, except looking at the source/disassembly of the offending
function. However, exception 107 I've put in mostly where I need to
say "this is not a fixnum!", which is quite a few places. Most likely
you've struck upon some operator (such as +) that's compiled without
knowledge of bignums. It's on the near-term todo.

256K is a limit you won't be able to fix very soon. But I'm in the
process of fixing this. I'll be away on holiday over this weekend,
though.

I most certainly do not mind code contributions :-)
