This isn't a bug.  It is an intended feature that chain.from_iterable evaluates lazily (and is documented as such).  The pure python equivalent in the docs behaves the same as the C version does.

Also, it is a long standing feature of lists that you can loop over them while mutating them (I've seen more than a few pieces of code that take advantage of that feature).
