             Bug #: 13084
           Summary: Clang should warn when namespace isn't closed in same
                    header
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: jyasskin at google.com

    Classification: Unclassified


$ cat test.h
#include <string>

namespace foo {
std::string bar() { return "Hello World"; }

// Forgot to close namespace.
$ cat test.cc
#include "test.h"

#include <vector>

$ clang++ -c test.cc

...  // >20 errors


It's not immediately obvious that this error spew is caused by the missing '}'
in test.h, since test.h isn't mentioned in the messages.
