Re: minloc/minval on empty array

Same with 4.3.

This is a bug. From the Fortran 2003 standard (13.7.78 MINLOC):

"Case (ii) The result of MINLOC (ARRAY, MASK = MASK) is a rank-one array
[...]
If ARRAY has size zero or every element of MASK has the value false, all
elements of the result are zero."

"Case (iii) If ARRAY has rank one, MINLOC (ARRAY, DIM = DIM [, MASK =
MASK]) is a scalar whose value is equal to that of the first element of
MINLOC (ARRAY [, MASK = MASK])."

Can you fill a bugreport (including quoting this part of the standard)?

Tobias
