Fixed by r11-1571 which was also backported to the gcc-10 branch.

Jason, was this fixed by the change to tsubst_pack_expansion? Should it be
added to the testsuite before closing it?

The problem seems to exist in gcc 4.7.3 and within the recent 4.9.0 trunk. The
following variant of the code removes unnecessary library dependencies and
constexpr (which is not needed to reproduce the problem):

//--
template typename T
struct foo
{
};

template int N, typename T, typename ...Us
bool bar(T , Us ...)
{
return false;
}

template int N, typename T, typename ...Us
bool bar(fooT , Us ...)
{
return true;
}

int main()
{
bar0(fooint(), 1, 2);
}
//--
