The code dates back to 1997.  I checked what GMP tehse days does and
this is what we should do in libgcrypt too:

  1. Call a function to handle case.
  2. Do a divide by zero in this function.
  3. If we are still alive abort or rais a signal.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
