What kind of failure?

Indeed.

Please avoid using "wtf" in this kind of discussion.
About the issue itself, I saw it too but didn't bother investigating it.
No big deal anywayy.

I would be happy to apply a patch.

We are aware of this and we decided to take this approach on purpose for
now. This is not perfect but as rust is a moving target,
we took this shortcut. We hope they will be able to improve/fix that
upstream in the near future.
