Compiler aborts while building one of our internal benchmarks with following
build error:

trunk/llvm/lib/LTO/LTO.cpp:335: llvm::Error
llvm::lto::LTO::addRegularLTO(std::unique_ptr<llvm::lto::InputFile>,
llvm::ArrayRef<llvm::lto::SymbolResolution>): Assertion `ResI != Res.end()'
failed.

I shall try to come up with a test case.
