            Bug ID: 77592
           Summary: GCC: Compile failures with delegated constructor
                    circular reference
           Product: gcc
           Version: 5.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gawain.bolton at free dot fr
  Target Milestone: ---

GCC seg faults with a program which uses delegated constructors with a circular
reference.

Tested using http://melpon.org/wandbox

Compilation segfaults using gcc v5.3, v6.1 and gcc HEAD 7.0.0 20160913

Simplified program is as follows:

struct T
{
    T(const int i,
      const char * s)
    : T(s,i) 
    { }

    T(const char * s,
      const int i)
    : T(i,s)
    {  }
};


int main()
{
    T t{"fred",2};

    return 0;
}
