           Summary: crash calling getSourceRange
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: nlewycky at google.com
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com

Try calling getSourceRange() on every AST node in this short program:

  template<typename _CharT, typename _Traits, typename _Alloc,
           template <typename, typename, typename> class _Base>
  class __versa_string : private _Base<_CharT, _Traits, _Alloc> {};

The problem is the TemplateTemplateParmDecl which has a NULL TemplateDecl
member. I don't think that's supposed to be possible.
