Hi James, Looking at: %7 = invoke i8* (...)* bitcast (i32 (%struct._Unwind_Exception*)* @_Unwind_RaiseException to i8* (...)*)(i64* %6) to label %8 unwind label %.finally_pad ; <i8*> [#uses=0] 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 the invoke instruction, not from a frame that contains the invoke instruction. Garrison...
