[Bug c++/35387] New: __PRETTY_FUNCTION__ produces inconsistent output

["d dot frey at gmx dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Minimal example program:

#include <iostream>
#include <algorithm>

template< typename T > struct A;

template< typename T, typename U > struct A< std::pair< T, U > >
{
  static void f()
  {
    std::cout << __PRETTY_FUNCTION__ << std::endl;
  }
};

int main()
{
  A< std::pair< int, int > >::f();
}


Output of __PRETTY_FUNCTION__ from this program:

static void A<std::pair<_T1, _T2> >::f() [with T = int, U = int]

Problem:

_T1 and _T2 are printed as the pair's parameter names, but it then say T=int
and U=int.

Additional information:

This only seems to occur with partial specialization.
