Hello.

I can reproduce this, but not always:

In my case, there is some correlation between failed build log and low
memory (I'm using different sized autobuilders).

But in either case, look at the error message. It's essentially like
this:

/usr/bin/install -c -m 644
  some-files _generated/errors.py some-files _generated/errors.py some-files directory

This fails because _generated/errors.py is listed twice.

You can trigger a similar error this way:

install /bin/ls /bin/ls /tmp

So, instead of trying to reproduce this, I would read the source code
and the makefiles and would try to determine under which circumstances
could _generated/errors.py appear twice in the install command line,
because that's what's happening here and what triggers the error.

Maybe that's easier than trying to reproduce it.

I would also forward this upstream. If both Lucas and me have found it
independently, then it seems a real problem to me.

Thanks.
