# This test can fail with libc with buggy getopt() implementation.
# If getopt() wants to parse multi-option args (-abc),
# it needs to remember a position withit current arg.
# it needs to remember a position within current arg.

# If this position is kept as a POINTER, not an offset,
# and if argv[] ADDRESSES (not contents!) change, it blows up.
