            Bug ID: 58639
           Summary: ICE on self-referential struct member
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dirtyepic at gentoo dot org

#include <vector>

struct node
{
    node &parent;
};

void f()
{
    std::vector<node> v;
    v.push_back({});
}

$ g++ -std=c++11 487010.cxx
g++: internal compiler error: Segmentation fault (program cc1plus)

ICE with trunk, 4.8.1, 4.7.3, and 4.6.4 with -std=c++0x.  4.5.4 correctly gives
an error.
