            Status: NEW
          Severity: critical
          Priority: P2

struct Ma(T){

  pure T alpha() const{ return 1.1; }
  Ma opBinary(string op)(in Ma m) const if(op == "-"){ return Ma(m); }
}

struct Pa(T){

  Ma!T _m;
  alias _m this;
}

pure T foo(alias P, T)(in P!T p){ return (p - p).alpha(); }


void main(){

  Pa!double p1;
  foo(p1);
}


This is as far as I could narrow it down.  Something starts to go wrong when
'opBinary' is called.  Also, removing pure from 'foo' doesn't cause the seg
fault.

DMD 2.56, Linux-64bit
