https://issues.dlang.org/show_bug.cgi?id=20701 Issue ID: 20701 Summary: extern(C++, class|struct) should not apply to inner types Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: pro.mathias.lang@gmail.com Consider the following code, compiled with DMD 2.091.0 on Windows x64: ``` extern(C++): extern(C++, class) struct Container { struct Inner { int val; } } void foo (const ref Container.Inner); pragma(msg, foo.mangleof); ``` This will output: `?foo@@YAXABVInner@Container@@@Z` which demangles to `void __cdecl foo(class Container::Inner const &)`. However, `Inner` is not a class, it is a `struct`, and having a similar declaration in C++ will lead to mangling errors. -- |
