            Bug ID: 58873
           Summary: [c++11] ICE with __underlying_type for broken enum
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet (compiled with "-std=c++11") triggers an ICE
since GCC 4.7.0 (when __underlying_type was introduced):

===================================
enum A : enum { };

template<typename> struct B {};

B<__underlying_type(A)> b;
===================================

bug.cc:1:17: error: underlying type '<anonymous enum>' of 'A' must be an
integral type
 enum A : enum { };
                 ^
bug.cc:5:22: internal compiler error: Segmentation fault
 B<__underlying_type(A)> b;
