I'm able to repeat this problem on Win 7 64 bit. Stepping through the code line by line it seems to be crashing at

  static CVKeyIndex *getCVKeyIndex(EditNurb *editnurb, void *cv)
  {
  	return BLI_ghash_lookup(editnurb->keyindex, cv);
  }

in editcurve.c. While editnurb is not null, editnurb->keyindex is, so the downstream functions are referencing a null pointer, and crashing.
