Assertion fails at virtual destructor declaration

[zeule]

The tool crashes on failed assertion when there is a virtual destructor in a C++ class declaration:

ClangSharpPInvokeGenerator: /usr/lib/llvm/12/include/clang/AST/GlobalDecl.h:61: void clang::GlobalDecl::Init(const clang::Decl*): Assertion `!isa(D) && "Use other ctor with dtor decls!"' failed.

clang/llvm version 12.0.0, .NET Core 5.0

Example C++ file:

#ifndef INC_GUARD
#define INC_GUARD

struct IFace {
    virtual ~IFace() = 0;
}; 

#endif
