You didn't cause any trouble --- this has be bugging a few of us for a while, already. A couple of weeks ago, we exchanged a dozen emails with Thomas and Gael. I didn't change anything. If tests are passing again, I would just suspect plain luck / something that made the bug no longer be triggered, just like it appeared someday for no good reason, but it must still be latent. Indeed, if, as I suspect, it's just a bad FP compare failing or succeeding depending on the desiderata of extended FP precision, then it can be extremely capricious!!
