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:
