            Bug ID: 58701
           Summary: [4.9 Regression] [c++11] ICE initializing member of
                    static union
           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 valid code snippet (compiled with "-std=c++11") triggers an ICE
on trunk (since at least 4.9.0 20130920):

===============
static union
{
  union
  {
    int i = 0;
  };
};

Isn't this by any chance invalid?  Anonymous aggregates cannot have members
with constructors.
