FWIW, ISO has a ptrdiff_t, which may be useful here.

That was pseudocode, I wasn't actually planning to rely on a function.

That was pseudocode, I wasn't actually planning to rely on a function.
Something more like
longdiff;
diff = stack_base_ptr - &stack_top_loc;
if (diff < 0)

GUC variable max_expr_depth that is intended to prevent this sort of
problem for the particular case of overly complex arithmetic
expressions, but it's diffic
