Stack im sync how to?

Say you’re debugging a program that is messing around with the stack that is leading to a software failure. Is there’s a tool that trace each time a register is pushed into the stack and retrieved from the stack (or many) to be able to track down such bug? I’m not sure I’m clear...

No. If the number of register pops is not identical to the number of register pushes, you would typically crash by running into a return address that isn't one. But at that point, it is already too late. If the "return address" is invalid, the MuGA will give you a hit. WIth a stack traceback, you have a chance that you know at least parts of the call-path.

Ok I found the issue, there was a movem to the stack but the minus before (sp) was missing

I didn’t understand why the program crashed randomly, in fact it was working by chance because the version number of intuition, graphics and diskont library were not set !!!
