           Summary: assertion failure with C++ namespaces
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: kremenek at cs.stanford.edu
                CC: llvmbugs at cs.uiuc.edu


The semantic analyzer crashes on the following input (also attached):

  long long f(long long);

  namespace __gnu_cxx {
    inline long long   f(long long __x) {}
  }

What we see:

$ clang t.cpp

Assertion failed: (( (isa<ObjCMethodDecl>(DC) &&
isa<TranslationUnitDecl>(CurContext)) || DC->getParent() == CurContext ) &&
"The next DeclContext should be directly contained in the current one."),
function PushDeclContext, file SemaDecl.cpp, line 48.
