#182 compiler crash: popType called with empty stack

[B S]

In nice-0.9.12 if I add an optional parameter to one of
my base class custom constructors, I get a compiler
crash in the linking step. If I just add a second
custom constructor, then there is no problem. If you
need the code, I can post it.

Stack trace:
