Your brain is absolutely right; mine's still in holiday mode.  :-)

Not sure what's going on then.

S'oh boy.  My previous ‘good’ output was built on ext4.  Here's 
what building 1.0.1 on btrfs (and 4 cores) gave me.  Safe to say 
this package isn't exactly deterministic there.

That's 3 very different possible outcomes so far.  My emptiness is 
reproducible on this machine, though.

I've pushed your patch (without the note about it not working 
since It's Complicated and there's no need to justify a bump 
anyway) as 93b3ef1966f9860ae88b87263f8c7f6052565c3f.  It's now 
reproducible on all my file systems, but feel free to try more. 
Thanks!

Kind regards,
