Indeed, there seems to be an issue with 32-bit systems which is being debugged at https://lists.freedesktop.org/archives/xcb/2016-June/010795.html
I agree that we’ll want to hold off on updating libxcb until there’s a fix for that issue (potentially even a new minor release if that arrives in a timely manner). Is that the issue you had in mind, or are there others which I didn’t spot?
