            Bug ID: 19980
           Summary: ICE during LinkageComputer
           Product: clang
           Version: 3.4
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal

    Classification: Unclassified

When compiler below codes using clang 3.4, clang will ICE. I think we should
issue an msg or build pass. NOT ICE.

void f(int i)
{
  extern int i;
}


clang: /home/qshanz/work/source/llvm/tools/clang/lib/AST/Decl.cpp:1205: static
clang::LinkageInfo clang::LinkageComputer::getLVForDecl(const
clang::NamedDecl*, LVComputationKind): Assertion `!Old ||
Old->getCachedLinkage() == D->getCachedLinkage()' failed.
