IndexError: list index out of range
This is triggered by an early override of sys.argv when usage() is called
(Lib/profile.py:603):
if not sys.argv[1:]:
parser.print_usage()
sys.exit(2)
(options, args) = parser.parse_args()
sys.argv[:] = args
if (len(sys.argv) > 0):
sys.path.insert(0, os.path.dirname(sys.argv[0]))
run('execfile(%r)' % (sys.argv[0],), options.outfile, options.sort)
else:
parser.print_usage()
return parser
In the "else" branch it tries to print usage but sys.argv[] were already
overwritten.
Attached is the proposed patch (tested with 2.5, 2.6, 3.1).
