--- Comment #64 from kilobug@kilobug.org --- Great news !
I tried the -wip branch, and so far no crash (with and without hyperz). I will keep running it and see how it works. I'll do more tests during the week-end, and hopefully they won't crash.
I don't know if I fumbled in applying the patch manually (would surprise me, but not impossible) or if there is another fix in the branch.
