Added the attached printfs. Here's the output:

This is a buffer overrun by one byte. You can see clearly that all the
other color depths (besides DeviceGray) add an extra byte to account for
this overflow. Only the DeviceGray one does not, adding one to the
data_length calculations for DeviceGray fixes the problem.

Please let me know if you want any other printfs or information in
specific places.
