I am not sure this is going to work, at least from the way I've played with the system. In my examples the _Unwind_RaiseException(...) is called from a frame (function) called via<br>
the invoke instruction, not from a frame that contains the invoke instruction.<br>

I'm pretty sure this doesn't matter. It seems to me more likely that the<br>
exception object was not initialized properly.<br></blockquote><div>Hmm. I've tried a bunch of different ways of creating the exception including calling a C++ function that then does a throw. If I understand right, the personality function should still be offered the foreign exception so it has a chance to call cleanups?<br>
