           Summary: clang::DiagnosticInfo::getArgKind(unsigned int) fails
                    assertion
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

template <int I> void Foo () { }

void Bar ()
{
  Foo <0x80000000> ();
}

triggers the following assert when trying to compile with Clang built from
trunk r116802:

/tmp/a.cc:5:8: warning: clang:
/work/llvm/tools/clang/lib/Basic/../../include/clang/Basic/Diagnostic.h:864:
clang::Diagnostic::ArgumentKind clang::DiagnosticInfo::getArgKind(unsigned int)
const: Assertion `Idx < getNumArgs() && "Argument index out of range!"' failed.

(Stack trace attached.)

This seems to be a regression from r116058, where the code compiles.
