Thanks Philippe,

So that means we have a bug in the objc side if this is actually happening on Darwin (which is a completely different issue…) That should be a radar against Foundation and I definitely think that may very well be a bug… 

I have been filling a radar https://bugreport.apple.com/web/?problemID=36107307 <https://bugreport.apple.com/web/?problemID=36107307>
I do think you are right it's a bug in the Objc Foundation… and trying to solve it in "swift-corelibs-foundation" was a mistake :)

Setting the locale globally was just a temporary test.

But i do think that it triggers a serious question:  Should all your tests be ran on all the available locales? 
You will certainly find a smarter solution …
