No I don't have any and I didn't find the webpage explaining how
to proceed. Do you have it ?

It seems that I have missed them. As you might have seen, I've made
these patches two months ago and I don't remember them failing at
that time. I've rebased and checked quickly before opening this
discussion. I should have checked more, my bad...
Moreover, there is a lot of tests already failing in the testsuite
(not with gas actually). Thus, I'm "fixing" them in several other
patches. But I don't want to push them as I still don't know
the root cause.
I'll check your patch also.

Thanks,
Clément
