Bug ID: 17655
Summary: [-cxx-abi microsoft] Assertion `FD->isUsed() && "Sema
didn't mark implicit function as used!"' failed
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Frontend

sema-mark-used.cpp
This is probably distinct from http://llvm.org/bugs/show_bug.cgi?id=10480, but
it trips the same assertion. I bet it has to do with our handling of complete
vs. base dtors in GetAddrOfCXXDestructor with the MS C++ ABI.
clang: ../tools/clang/lib/CodeGen/CodeGenModule.cpp:1392: llvm::Constant
*clang::CodeGen::CodeGenModule::GetOrCreateLLVMFunction(llvm::StringRef,
llvm::Type *, clang::GlobalDecl, bool, llvm::AttributeSet): Assertion
`FD->isUsed() && "Sema didn't mark implicit function as used!"' failed.
