           Summary: Error message "instantiated from here" gives wrong
                    location
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: reichelt at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

Consider the following invalid code:

----------------------------------------------
     1	template <int> struct A
     2	{
     3	    static const int i=0;
     4	};
     5	
     6	int baz() { return A<0>::i; }
     7	
     8	struct B
     9	{
    10	    static void foo (int);
    11	};
    12	
    13	template <typename T> struct C
    14	{
    15	    virtual void bar() const { T::foo(); }
    16	};
    17	
    18	C<B> c;
----------------------------------------------

Compiling this with g++ gives the following error message:

file.cc: In member function `void C<T>::bar() const [with T = B]':
file.cc:6:   instantiated from here
file.cc:15: error: no matching function for call to `B::foo()'
file.cc:10: note: candidates are: static void B::foo(int)

The line number "6" in line 2 of the error message is obviously bogus.
It should read "18" instead.
The bug happened to me in a more complex situation where even the
file name was wrong. In such a case it is very difficult to find the
point of instantiation by hand. :-(

All versions since 2.95.x seem to be affected (including 3.3 branch and
mainline).
