Description Charlie 2014-03-19 07:34:13 UTC 
The following causes a segfault on gcc 4.8.1 and earlier versions:

template <typename... Args>
struct X
{
  template <typename Head, typename... Tail>
  using First = Head;
  
  using Y = First<Args...>;
};

This got fixed with r201469 on the trunk.
Comment 2 Paolo Carlini 2014-12-12 19:06:17 UTC 
Closing then.
