 You mean convert the two 'tor_assert()' by 'if' statement? I did that. It
 works… At least it doesn't crash the Tor process ! Thanks !

 I don't know if it's relevant but on OpenBSD, if the strtol() is too
 complicated to manage, there is strtonum() alternative which is meant to
 be simpler :


  STANDARDS
      strtonum() is an OpenBSD extension.  The existing alternatives, such
 as
      atoi(3) and strtol(3), are either impossible or difficult to use
 safely.
