Thanks for the new test case. Bjorn's law - "If it isn't tested,
it doesn't work" - has again been proved. :-)

Your other code example is not complete, so I haven't verified, but
it seems to be the same bug that I have already fixed.

The attached patch should fix all found bugs in beam_bsm.erl. It
should be applied to the unchanged beam_bsm.erl in R12B-0.
