More information:

I checked out the trunk and checked it again. The bug is still present, but
while testing it, I noticed that the problem does not occur with my own types,
only with types from the standard library. Here's the code I used:

#include <algorithm>

template< typename X, typename Y > struct P {};

template< typename > struct A;

template< typename T, typename U >
struct A< P< T, U > >
{ static void f() { int i; } };

template< typename V, typename W >
struct A< std::pair< V, W > >
{ static void f() { int i; } };

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

and the output is:
