>How-To-Repeat:

Save this file
============================ foo.cc ======================================
template <char *p>
struct Offset {
  int x;
};

char pool[] = "Eins\0" "Zwei";

struct Temp {
  char *q;
  Temp (char *s) : q (s) {}
  template <char *p> operator Offset<p> () const { return (Offset<p>){x: q-p}; }
};

Offset<pool> offsets[2] = { Temp(pool+0), Temp(pool+5) };
===========================================================================

and run "g++ -S foo.cc".
