Bug ID: 41578
Summary: test/std/utilities/variant/variant.get/get_type.pass.c
pp has workaround for a non-bug
Product: libc++
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: zi...@kayari.org
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
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 https://bugs.llvm.org/show_bug.cgi?id=15481
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
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87603 so this test fails with G++
now as well.
