- Sounds like MAYBE a stack overflow. Are you using a lot of recursion?
- Unlike *nix the amiag does NOT have an infinite stack. Standard stack
- is 4k and can be set to as much as memory will allow but whatever it is
- set to - that is IT.
-
- So if you are using a lot of recursion the moral is - DONT use more
- automatic variables than you absloutely HAVE to - allocate everything from
- the system memory pool.
-
- BTW I would be VERY interested in seeing the results of your efforts.
