* [Bug c++/115417] New: Destructor is noexcept even though the class has a throwing destructor subobject in an anonymous union @ 2024-06-10 16:33 janschultke at googlemail dot com 2024-06-10 16:35 ` [Bug c++/115417] " pinskia at gcc dot gnu.org ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: janschultke at googlemail dot com @ 2024-06-10 16:33 UTC (permalink / raw) To: gcc-bugs https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115417 Bug ID: 115417 Summary: Destructor is noexcept even though the class has a throwing destructor subobject in an anonymous union Product: gcc Version: 15.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: janschultke at googlemail dot com Target Milestone: --- Consider the following code: #include <type_traits> struct D { ~D() noexcept(false); }; struct B { union { char c; D d; }; ~B() {} }; static_assert(std::is_nothrow_destructible_v<B>); This assertion passes only for GCC, but not for other compilers (https://godbolt.org/z/e5jEKzjfs). I believe GCC is wrong because 'd' is a potentially constructed subobject of B (https://eel.is/c++draft/except.spec#8) and therefore, a destructor without a noexcept-specifier should be potentially throwing. This bug could be related to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109768, but I don't think it is a duplicate. ^ permalink raw reply [flat|nested] 4+ messages in thread
