In the program snippet given below, line number 14 and 20 should have identical access privileges with respect to A::func(). But gcc 4.1.2 compiles line #14 just fine, whereas on line #20, it catches the error correctly. This bug is similar to bug #24118.

  1 class A
  2 {
  3   protected:
  4     void func ()
  5     { }
  6 };
  7
  8 class B: private A
  9 {
 10   public:
 11   template <class T>
 12   void foo ()
 13   {
 14     void (A::*ptr)() = & A::func;
 15    // Should not compile but compiles on gcc 4.1.2
 16   }
 17
 18   void bar ()
 19   {
 20     void (A::*ptr)() = & A::func;
 21     // Should not compile and gcc throws error.
 22   }
 23 };
 24 int main (void)
 25 {
 26   B b;
 27   b.foo<int>();
 28   b.bar();
 29 }
