Sorry I can't really look into this atm, but if Kai is right, the
tests I sent in the below link may reproduce as they set breakpoints
on objc methods in shared libraries, maybe with some coercing to avoid
the ambiguity problems e.g. using a unique method name

I still need to update it to reflect Joel's comments later in the thread though
will get back to this when I can budget in some new hardware.
