How much memory may a HPPL program use on a G2?

Try disabling parts of the code that you suspect might be filling up the stack.

If you are referring to the data stack, that CAN be the problem, but it's usually not, because the Prime's "history stack" is limited to 128 items (a little-known fact), unlike RPL's "infinite stack". Of course, if the objects on Prime's data stack are gargantuan (e.g. huge matrices or lists or algebraic expressions), yes, that can use up all your free memory.

However, if you are referring to the program environment's return stack, then yes, it's easy to unintentionally create a bottomless subroutine hole, or a recursive routine that gobbles up memory. A listing of the program is needed to find memory leaks like these.
