ISSUE:       1420
TITLE:       Local buffer overrun in DYN_error() that takes down the server
DESCRIPTION:
  We have a local buffer overrun in DYN_error(), while copying tdbb_status_vector to
  local_status. It seems to be the first time (DYN errors + stack trace facility) when 20
  status words are not enough to store the complete error info.
