Source, output and gdb backtrace
This program:
#include <tuple>
template<class X, int Y>
struct a: public X{
using X::X;
};
int main(){
auto x=a<std::tuple<int, int>, 42>();
}
makes clang crash.
The problem doesn't happen with libstdc++.
The problem is in the assignment - without it the program compiles fine.
The problem only happens with two-argument tuples.
The problem only happens when the Y parameter is non-class.
The problem does not depend on the value of Y.</pre>
