From: "foobarandfoo at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/105452] New: static_assert inside nameless nested union: invalid "inaccessible within this context" error Date: Mon, 02 May 2022 11:27:55 +0000 [thread overview] Message-ID: <bug-105452-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105452 Bug ID: 105452 Summary: static_assert inside nameless nested union: invalid "inaccessible within this context" error Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: foobarandfoo at gmail dot com Target Milestone: --- template <typename T> struct C { union { char v; static_assert(sizeof(v) == sizeof(char), ""); }; }; int main() { C<int> x; } Fails to compile in every version I tried (including 13.0, 11.3.0, 11.2.0, 11.1.0, 10.3, 9.4) with "error: ‘char C<int>::<unnamed struct>::v’ is inaccessible within this context static_assert(sizeof(v) == sizeof(char), "");". If we modify struct C to be non-templated, the code compiles successfully. Clang and MSVC compile the initial code. https://godbolt.org/z/j171x1aGz
