Like the last one was/is the inability to comprehend safety of large buffers on ppc64el because the stack clash protector code generated by gcc isn't understood. The one before that was more problems of that sort on armhf where it also didn't understand the clash protector - in more cases.

It's quite surprising and it takes days to weeks to debug each of these, going down to the assembler level and verifying that by hand.
