[Bug 1060059] Re: Xorg crashed with SIGABRT in ResFindAllRes()
I've just put a load of comments on the upstream bug The short story is that a patch to Xext/xres.c ResFindAllRes to change counts[(type TypeMask) -1]++ to if ((type TypeMask)!=0) counts[(type TypeMask) - 1]++; stops the crash. The longer story is, I don't think that case of a 0 type should be reached, but I don't know about the innards of X to be sure. I've commented one case on the upstream bug and how to stop it, and also a suggestion to make it safer to stop it triggering. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1060059 Title: Xorg crashed with SIGABRT in ResFindAllRes() To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1060059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
