             Bug #: 53816
           Summary: internal compiler error: tree check: expected
                    field_decl, have identifier_node in
                    fixed_type_or_null, at cp/class.c:6419, with
                    -std=c++11 option
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

preprocessed source file

The attached code looks innocent but causes ICE with GCC 4.8.0 20120624
(experimental) and `-std=c++11' option, although it doesn't rely on any C++11
feature. And without `-std=c++11' option, it successfully compiles.

Note that the attached code successfully compiles with GCC 4.6.4 20120622
(prerelease) and 4.7.2 20120623 (prerelease), regardless of whether
`-std=c++0x' option is used.
