I'm far from an expert, but I might have an idea. The question is: must
this works for embedded version of Python, or can I fool around with
main()?
Here's the approach:
- In main(), get the address of some local variable. Call this
min
- Call getrlimit, and see the stack size. Call max = min+ (<stack size )
- When checking for "too much recursion", take the address of a local
variable and compare it against max. If it's higher, stop.
