the following code compiles on i386, but not for x86_64:

tim@laptop:~$ g++ -m32 bug.cpp 
tim@laptop:~$ 
tim@laptop:~$ g++ -m64 bug.cpp 
bug.cpp: In function ‘int main()’:
bug.cpp:69: error: no matching function for call to
‘get_samples(my_table<float, 1024u>&)’
tim@laptop:~$ 

#include <boost/array.hpp>

typedef unsigned int uint;

template<typename sampletype, uint size>
struct my_table:
    public boost::array<sampletype, size>
{};

template<typename sampletype, uint size>
inline const sampletype * get_samples(boost::array<sampletype, size> const &
buffer)
{
    return buffer.begin();
}

int main()
{
    my_table<float, 1024> tab;
    const float * ptr = get_samples(tab);
}


i could reproduce it with the debian packages of gcc-4.1 and 4.2 on i386 and
amd64. 

best, tim
