[Tioga-users] Fwd: bug tioga?

  Hello,

  I've just received this message about a bug in Tioga. It is in
french, but the backtrace should be clear enough ;-)... I think this
bug arises because there is an undetected and non-destructive buffer
overflow somewhere in the code that is detected by pointer
instrumentation in the libraries linked to on this guy's machine.

  I won't have any chance to tackle it before next Thursday, so feel
free to squash it before I'm back ;-)...

  Cheers,

      Vincent

Salut Vincent,
Si tu n'as pas le temps de regarder ca, c'est pas grave.
Désolé de te déranger. Je viens d'installer ruby, tioga et ctioga sur
une machine.
J'ai donc récupéré les dernières versions.
Sur une autre machine, j'ai un script qui fonctionne très bien
(ruby 1.8.5, tioga 1.6, ctioga 1.6)
Le même script avec la nouvelle config plante
(ruby 1.8.6, tioga 1.6, ctioga 1.6.2)
J'ai downgradé ctioga en 1.6, même bug. Ca viens de la nouvelle
version de ruby (1.8.6)?
Voilà le msg d'erreur:

*** buffer overflow detected ***: ruby terminated

Mon fichier est clean et même la simple commande:
