[fpc-pascal] Validate heap/stack addresses

[Bruce Bauman]

I'm trying to port/debug some ugly Pascal code.

 

Is there a way I can tell if an arbitrary address is within the heap or
stack?

 

I want to do something like:

 

Assert(ValidHeapAddress(a))

Assert(ValidStackAddress(a))

 

to catch potential errors in the code.

 

I'm guessing any address between "end" and the current brk is a valid
heap address.

 

Thanks.
