I understand your argument, but there are other arguments that are, I think, at least equally valid and convincing. As I said, MINVAL basically ignores NaNs, so an array containing only NaNs is equivalent to an empty array: its MINVAL is +Huge. Note that having MINVAL = +Huge is, in itself, a telltale sign that something is wrong, if there is no mask present. Now, I have another question: what happens for mixed NaNs? For example, in your scheme, what would be the value of MAXVAL((/sNaN, qNaN/))? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30694
