Created attachment 125134 [details] [review] patch to fix this issue If one of the query functions fail, xvinfo does not properly handle these cases and will most likely run into a segmentation fault due to accessing uninitialized variables (which includes pointers).
Thanks for the patch, pushed now: To ssh://git.freedesktop.org/git/xorg/app/xvinfo b792adf..b086401 master -> master
