Thanks for testing! It's good to hear it solved your problem. :)

Hmm.. I think it should check type of anon mapping too (assuming JIT
interface only provides function symbols, no?):
if ((anon || no_dso) && type == MAP__FUNCTION)) {

And it should be simply:
if (type != MAP__FUNCTION)

I'll update this and send a formal patch soon. Could you please test it with
the new patch then?
