on 32-bit platforms gcc and nvcc disagree about the size of tuples of pairs

What steps will reproduce the problem? This test program:

include

include <tr1/tuple>

include

int main() { std::cerr << "sizeof(long long): " << sizeof(long long) << std::endl;

using namespace std; using namespace std::tr1;

typedef pair<long long, long long> p; typedef tuple<p, unsigned int> t;

std::cerr << "sizeof(tuple<pair<long long, long long> >, unsigned int>): " << sizeof(t) << std::endl;

return 0; } What is the expected output? What do you see instead? The size is 20 on gcc4.4.1 32-bit, 24 on gcc4.4.1 64-bit, and 24 on nvcc3.0b

This is a gcc issue not an ocelot issue.
