#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 ‘distance(foo()::my_iter,
foo()::my_iter)’
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.)
