I don't think it's a critical bug - it only appears on my hand written signal trampoline with a hand written CFI (what is a bit unusual situation :-). IMHO no std. glibc user should ever hit it. So I propose don't wait with merging your branch - I started to use it on my AMD64 machines and so far I can say it's very good :-) Michal Ludvig
