          Priority: P2

The libjpeg documentation (e.g. http://trac.imagemagick.org/browser/jpeg/trunk/libjpeg.txt) specifies:

[the empty_output_buffer method of a JPEGDestinationManager] "should write out the *entire* buffer (use the saved start address and buffer length; ignore the current state of next_output_byte and free_in_buffer)."

Fix jpegEmptyOutputBuffer() by ignoring free_in_buffer value as required.
