# Triggering the bug detected by this test requires a newline to fall

# we choose some value N, we also catch any D which divides N evenly
# (since we will read backwards in chunks of D). So we choose 8K,
# which catches glibc (with an 8K BUFSIZ) and *BSD (1K).
#
# Each line is 114 characters, so we need 75 to still have a few before the
# last 8K. The 89-character padding on the final entry lines up our
