Hmm, strange. What platform are you on?

I saw something similar *once* on Windows, but it then passed my tests
a lot of times in a row so I figured it was just a "didn't clean
properly" thing. Clearly there's a bug around.

What's the size of the latest WAL file that it did work on? Is it
16791960424 bytes? That's way way to large, but perhaps it's not
switching segment properly? (that value is supposedly the current
write position in the file..)

Oh yes, that's one of the main reasons to use it, so you should
definitely be able to do that!
