I'm guessing you are trying to rerun the original code that caused the exception? That isn't possible - once you've done a longjmp back to a calling function, you can't go back to where you were in a nested function. For finally, what I think you want to do is longjmp to the next exception handler in the stack. I hadn't originally thought of doing it that way, but it would probably be pretty easy. Also, strictly speaking, you aren't supposed to run any finally blocks unless there is an except handler that will ultimately handle the exception. > * I'm sure it is full of bugs. Reports welcome, and patches > more even so. I think __seh_push_handler and __seh_start_handler are not called in the right places. See my earlier email. Note that I think what haret has now is fine. So, I'm just following along out of curiosity.
