THis is a bug in scandir in 3.3 - having to do with how much memory
scandir will allocate to hold the directory entries. It gueses based on the
stat size of the directory using a heuristic designed for BSD FFS which
doesn't always work on EFS. If you simply add another entry to /bin it
will probably start working.

It has been fixed in 4.0
