How to detect stack overflow on CC65?

[KanedaFr]

Hi,

Are you aware of a way to detect stack overflow with CC65 ?

We allocated space memory on the config file using 

__STACKSIZE__:

 

but how do we know if it's enough or not ?

Of course, I doubt everything could be checked at compile time (recursive calls for exemple) so is there a trick to know our program eat all the stack ?

Something like using the last byte of the stack for example ....

You can fill the stack with a virgin pattern and then check from bottom to top until the first byte != virgin pattern.

 

You get both, check for overflow and actual usage.
