template instantiation problem with g++ 4.1

[Egon Kocjan <egon@xxxxxxxxxxx>]

Hello,

I have some code, which compiles with g++ 3.2-4.0 and msvc 7.x-8.x. It 
does not compile with the latest g++ 4.1.1. Example:

#include <vector>

inline void y(int i)
{
}

template <class T>
void y_iter(T begin, T end)
{
       for(; begin != end; ++begin)
               y(*begin);
}

template <class T>
void y(const std::vector<T> &v)
{
       y_iter(v.begin(), v.end());
}

void x()
{
       std::vector<std::vector<int> > z;
       y(z);
}

I get this error:
x.cpp: In function âvoid y_iter(T, T) [with T = 
__gnu_cxx::__normal_iterator<const std::vector<int, std::allocator<int> 
>*, std::vector<std::vector<int, std::allocator<int> >, 
std::allocator<std::vector<int, std::allocator<int> > > > >]â:
x.cpp:17:   instantiated from âvoid y(const std::vector<T, 
std::allocator<_CharT> >&) [with T = std::vector<int, 
std::allocator<int> >]â
x.cpp:23:   instantiated from here
x.cpp:11: error: cannot convert âconst std::vector<int, 
std::allocator<int> >â to âintâ for argument â1â to âvoid y(int)â

It seems as if symbol resolving has moved from template instantiation to 
template definition time (just like "normal" functions). Is there a way 
to avoid this issue for such recursive template instantiations? I have a 
lot of code that depends on this approach...

Thanks,
