It's been a while since this but GraphicksMagick is still an awesome tool.
I have an issue that is perhaps related to the issue described in the above link using 1.3.17-Q8. If I try to use a tiff file as a source that is CMYK, has some transparency and is saved with per-channel byte order and attempt to convert that image to an RGB image, gm.exe crashes.
Thanks for the interesting image file. On a Unix system here, I am not immediately seeing the crash but I am seeing distorted output in the white part of the image, which means something is definitely wrong. The image displays fine so the issue must be in the writer.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The fix for this was trivially easy. It was due to a typo on my part. The fix is in Mercurial as changeset 13861:1a2d7a38363f and will be in the next development snapshot and next release. Thanks for reporting it.

example command-line:
produces the following output.txt before the process crashes:

Thank you for fixing this, Bob.
It seems that the GraphicsMagick test suite needs to be improved in order to find issues like this.
