--- Comment #1 from vlukas at gmx dot de ---
Reduced testcase:
---------------------------------------------------
struct node {
  node &parent;
};

struct vector {
  node n;
};

vector v({});
--------------------------------------------------


The original testcase and the reduced one above produce identical backtraces
with gcc version 4.9.0 20130429 (experimental) (GCC):
