<div>
<pre>I got segfault compiling this code:
#include <utility>
template <std::size_t ...Ts>
struct Ice<std::make_index_sequence<sizeof(Ts...)>>
{};
I'm using clang 10.0.1, but I also reproduced the issue with clang 12 and trunk
on godbolt <a href="https://godbolt.org/z/5eEsvWdxd">https://godbolt.org/z/5eEsvWdxd</a>
The issue persists if I omit parameter pack expansion on line 4:
#include <utility>
template <std::size_t ...Ts>
struct Ice<std::make_index_sequence<sizeof(Ts)>>
{};</pre>
</div>
