   switch(t2) 
   { 
    default: 
    break; 
   } 
 
   switch(C1::t1) 
   { 
    default: 
    break; 
   } 
  } 
 }; 
}; 
-- BUG INFO --------------------------------------------------------------------------------------- 
Given the code above and running just g++ with no command line parameters I get: 
 
[root@home temp]# g++ boog.cpp 
boog.cpp: In member function `void C1::C2::fun()': 
boog.cpp:53: error: switch quantity not an integer 
boog.cpp:59: error: switch quantity not an integer 
 
I expected g++ to see the 'operator T() const'. Note that if you comment out '#define 
USE_TEMPLATE' then the code compiles OK.  
 
This problem occurs on other versions of GCC as well (notably 3.3). 
 
Cheers, 
Nick

Redux:

----------------------------------------------
template <typename T> 
struct A {
  operator int();
};
 
struct C1 
{ 
  static A<void> t1; 
 
  void fun() 
  { 
   switch(t1) 
   { 
    default: break; 
   } 
  } 
}; 
----------------------------------------------

Trivial fix in testing.
