Comment 7 for bug 1378888

I've tried to use PDb on Ubuntu/PPC64LE for debugging the issue.

However, with Pdb, the issue disappears...
We have in "opts" variable the correct value for fields: 'fields': 'first, last'

$ pdb ../../lang/py/build/scripts/avro cat /tmp/REIX --fields 'first, last'

build/scripts/avro: line 243:
  opts, args = parser.parse_args(argv[1:])

Pdb) c

The program finished and will be restarted

Launching the same command withoug pdb:
    ../../lang/py/build/scripts/avro cat /tmp/REIX --fields 'first, last'
raised the same issue:

{"first": "daffy"}
{"first": "bugs"}
{"first": "tweety"}
{"first": "road"}
{"first": "wile"}
{"first": "pepe"}
{"first": "foghorn"}
Usage: avro cat|write [options] FILE [FILE...]

avro: error: Can't open last - [Errno 2] No such file or directory: 'last'
