[Bug c++/19199] New: Wrong warning about returning a reference to a temporary

[lars at trolltech dot com]

Hi, 
 
The code below produces a warning about returning a reference to a temporary 
when using enum types for the qMin method. It works fine when using primitive 
types or classes instead of enums. 
 
Fortunately it's rather easy to work around the warning :) 
 
Best regards, 
Lars 
 
 
enum Foo { A, B }; 
 
template<typename T> const T &qMin(const T &a, const T &b)  
{ return a < b ? a : b; } 
 
int main(int,  char **) 
{ 
    Foo f = A; 
    Foo g = B; 
    Foo h = qMin(f, g); 
    return 0; 
}
