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 âint main()â:
bug.cpp:69: error: no matching function for call to
âget_samples(my_table<float, 1024u>&)â
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

Can you try to reduce this to something smaller that doesn't require
boost?

... i tried when reporting the bug ... however i haven't really been able
create a stripped down version ...
the problem also occurs when using std::tr1::array instead of boost::array,
though ...

This fails with both -m32 and -m64 (but I'm not quite sure if it
still reproduces the original issue):
typedef unsigned long size_t;
template<typename _Tp, size_t _Nm = 1> struct array { };
template<typename sampletype, unsigned int size>
struct my_table: public array<sampletype, size> { };
template<typename sampletype, unsigned int size>
inline const sampletype *
get_samples(array<sampletype, size> const & buffer) {
return buffer.begin();
}
int main() {
my_table<float, 1024> tab;
const float * ptr = get_samples(tab);
}

argument types are: (my_table<float, 1024U>)

Here is a reduced testcase which is rejected for both -m32 and -m64:
typedef unsigned long size_t;
template <typename t, size_t len> class array {};
typedef unsigned int uint;
template<typename sampletype, uint size>
struct my_table: array<sampletype, size> {};
template<typename sampletype, uint size>
inline const sampletype * get_samples(array<sampletype, size> const &buffer) {
}
int main()
{
my_table<float, 1024> tab;
const float * ptr = get_samples(tab);
}

Yes it does, I had missed your reduced testcase before.
