You know, that one I dont know for sure.  I had
assumed you would be able to.

Well I don't know exactly how exceptions are
implemented, but I'd imagine they would simply need
the frame pointer so they could go up the frame to the
C++ function with the try block.  Which would mean it
could go straight through C functions with frame
pointers.

But again, this is what I had assumed and I don't know
for sure.
