[Bug c++/45490] New: Confusing error message for local type arguments

[giecrilj at stegny dot 2a dot pl]

#include <algorithm>

void foo (void) 
{ 
class my_iter: 
 public std:: iterator <std:: random_access_iterator_tag, int > 
 { public: operator int * (void) const { return NULL; }}; 

std:: distance (my_iter (), my_iter ()); }

Compiling this code, you get:

error: no matching function for call to &#8216;distance(foo()::my_iter,
foo()::my_iter)&#8217;

This message is highly confusing.

Both Intel and Comeau give the following message:

a template argument may not reference a local type

(Microsoft groks the construct all right.)
