--- Comment #20 from Josh Poimboeuf <jpoimboe at redhat dot com> --- Thanks very much to everyone who has looked into this so far. It would be very helpful to get answers to the following questions, so we can understand the impact to the kernel: 1) Is there a reliable way to avoid the bug, either in code or with a gcc flag? 2) Is there a reliable way to detect the bug by looking at the object code?
