        <pre>In the two tests
std/utilities/variant/variant.get/get_type.pass.cpp
std/utilities/variant/variant.get/get_index.pass.cpp
you do:

    using V = std::variant<int, const long>;
    constexpr V v(42);
#ifndef __clang__ // Avoid <a class="bz_bug_link 
          bz_status_RESOLVED  bz_closed"
   title="RESOLVED INVALID - noexcept should check whether the expression is a constant expression"
   href="show_bug.cgi?id=15481">https://bugs.llvm.org/show_bug.cgi?id=15481</a>
    ASSERT_NOEXCEPT(std::get<int>(v));
#endif

That isn't a Clang bug (it was closed as INVALID). Since C++17 constexpr
functions are not implicitly noexcept, and Clang considers that a DR against
C++11 and C++14 too.

G++ 9 now has the same behaviour, changed recently by
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87603">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87603</a> so this test fails with G++
now as well.</pre>
