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 âÂÂint main()âÂÂ:
bug.cpp:69: error: no matching function for call to
âÂÂget_samples(my_table<float, 1024u>&)âÂÂ
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
