Yep, that's old; according to <http://flex.sourceforge.net/>:

  March 3, 2003
    flex, version 2.5.31.
    Later releases have made this release obsolete.  Only use if you
    have a particular need to avoid later changes.  In particular, bug
    and security fixes of general interest happened after this release.

So my suggestion would be to update your flex installation, and see
whether the issue persist.

Thanks,
  Stefano
