Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org

using namespace std;
template<typename ...T>

return make_tuple(t...);
}

IT could well be - I struggled to get a more minimal example when not using
'make_tuple', and it could well be doing something similar, especially if it
yields the same ICE. Does the sample code I give compile correctly with the
patch for PR51852?
