             Bug #: 13216
           Summary: C++11 crash 'isStruct() && "Invalid accessor"'
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal

Created attachment 8769
  --> http://llvm.org/bugs/attachment.cgi?id=8769
test case and crash backtrace

The attached source asserts with 'isStruct() && "Invalid accessor"'
at clang/include/clang/AST/APValue.h:302, using -std=c++11.
I'm on r159223, but the crash occurs with r155756 or later.
Although I expect that patch is not directly responsible.

With -std=c++03 it warns about '= default' as a C++11 extension,
but does produce an object file.

The test case is as reduced as I know how to make it; 4 layers of
templates, sorry about that! Taking any of them out made it go away.
