Trying to get trap/leave to work properly but the whole WINS stuff seems over complicated with a lot of assembly in the middle and it's not working on my compiler. When the throw happens the debugger complains about uncaught exception when I'm definitly inside a catch implemented by our TRAP.
I think I'm going to come up with a much simplified trap/leave implementation for SYMC. On my prototype all that stuff was working fine in like 20 lines of C++.
