Preprocessed test case.
Compiling the attached preprocessed source file with the command line in the
attached driver file produces this assertion failure:
clang-4.0: /work/sources/llvm/current/tools/clang/lib/AST/DeclBase.cpp:111:
void clang::Decl::setInvalidDecl(bool): Assertion `!isa<TagDecl>(this) ||
!cast<TagDecl>(this)->isCompleteDefinition()' failed.
The stack backtrace looks like this:
