--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Perhaps just tcl bug on your platform then? > Do you have some revision where you can reliably not reproduce the hang > (say with 100 invocations)? Otherwise I kind of don't understand > the Regression marking. Regtesting all languages on my machine takes between 4 and 5 hours (at -j8), so I never test any revision more than once. I typically do a couple regtestings every day and I have never seen any hanging before March 16 for trunk.
