# The literal width below is 2^31-1.
# I expect this usage of the printf program to fail.
# However, it depends on the C library printf function.
# It could conceivably output "1." and 2GB worth of '0's.
# You can provoke misbehavior with a much smaller width if you limit
# virtual memory via, e.g., ulimit -v 10000, but using ulimit would
# be tricky, since it's not portable.
