I am trying to simulate an old and perfectly working assembler program for a Mega16. I have recently upgraded to SP3 build 490, but now the simulator gives me "AVR Simulator: Excessive stack overflow, stop sim" at a specific program location. And the stack is not overflowed at all (only 6 bytes used).
The simulator also stops at another program line, but without any warnings or anything. Just like there was a breakpoint there, but there isn't.
Does this sound familiar to anyone?
Is there anything I can do to get my simulator to work again, apart from a total reinstall?
