Subject: rb_protect and longjmp

Looking for some insight about rb_protect and the longjmp calls.

Is rb_protect supposed to always return back to the caller?  I'm wrapping
calls in rb_protect wherever I can in my C++ application, but it seems that
rb_protect doesn't always return.
If I call rb_raise from inside rb_protect, longjmp seems to be getting
called and I don't get a return from rb_protect.  I also noticed that if I
make certain "mistakes" such as pass an invalid value to rb_funcall where
the object VALUE is expected, my application throws a system exception even
though the rb_funcall was wrapped in rb_protect and rb_protect never
returns.

I've poked around as much as I know how to, and I am not sure if this is
intended behavior (perhaps: caveat emptor), or if the bcc32 .dll build is
just snafu.
