Comment 2 Greg Farnum 2016-04-07 18:20:52 UTC 
There have been various issues with pybind that were fixed since that commit; John can confirm this is one.
Comment 3 John Spray 2016-04-07 18:57:03 UTC 
We did indeed fix this, it seems likely that this is a newer test running against older code.  The test was added at the same time as the fix.
Comment 4 John Spray 2016-04-07 21:24:31 UTC 
This was fixed upstream in the following commit:

commit 85cfa4f1d384b7bbbd811031b7013099aaafe706
Author: John Spray <john.spray>
Date:   Thu Mar 3 11:59:21 2016 +0000

    libcephfs: fix crash on getpwd
    
    ...if the directory has been unlinked in
    the background.  Previously this would
    assert out, now it will just give you
    the last string that you passed into chdir.
