--- Comment #3 from Andreas Radke <a.radke at arcor dot de> --- I moved away from XFS file system and so can't reproduce it anymore. The bug should be in XFS code probably triggering a change in gcc behavior. Feel free to close this one. note: we had a similar issue in libdrm. maybe it's related or not. this one is now fixed: http://cgit.freedesktop.org/mesa/drm/commit/?id=482abbfafb56cbceaf5355c026434e638cddd0f1
