--- Comment #3 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
I believe there was some confusion about the second testcase. The real question
is if this is valid in all cases:

MERGE(C_NULL_PTR, C_LOC(pc), .NOT.PRESENT(pc)))

and I believe it is not, because all arguments might be evaluated. However, it
is also OK not to evaluate all arguments for the reasons quoted.
