I wondered that as well for a while. The problem, IIUC is that the case-selector must be an initialization expression. I'm no language lawyer, but if I understand the F2003 (draft) standard, MAXLOC(k,1), where 'k' is a PARAMETER, ought to be a perfectly valid initialization expression. The standard, section 7.1.7, says on initialization expressions: "It is an expression in which each operation is intrinsic, and each primary is [...] (5) A reference to a transformational standard intrinsic function other than NULL, where each argument is an initialization expression," MAXLOC, is, AFAIK, a transformational standard intrinsic, and 'k' and 1 are, AFAIK, initialization expressions. It turns out, however, that the F95 standard has a slightly different definition of initialization expressions (in section 7.1.6.1); it seems that MAXLOC is not allowed here. So it seems the code is still invalid F95, and we should give a warning/error message if strict F95 standard checking is requested. I must, however, say, that I find it a bit wierd that MAXLOC isn't allowed in this context, so I'm not sure what to think here ... I leave this as unconfirmed for now. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25104
