Perhaps it only resolves instruction faults because you only resolve with
MAP__FUNCTION. You can try MAP__VARIABLE as well when that fails.

But that is going to only help with faults on global vars, ie: only
a few part of them. Further information would require some dwarf processing.

Your patch looks good though. Mind resending it with appropriate title/changelog
and signed-off-by tag?
