 		 #172326 - Have you confirmed that?
Responding to: ???'s previous message
Praveen Kumar said:
((void (code *) (void)) 0x0000) (); // Jump to 0x0000.

Have you confirmed that really does result in a Jump - and not a call?

Does it depend on the optimisation level used?

Does it depend upon whereabouts in your code you make the "call"?

etc, etc,...
