Hi,
First of all, big thanks for ArgyllCMS: the software is extremely good.
Thanks to ArgyllCMS I am re-discovering my passion for printing!
Today I found a bug, or at least an unexpected behavior. When running
colprof and applying gamut mapping ("-S AdobeRGB1998.icc"), I get
"segmentation fault - core dumped" after a few seconds of execution. The
problem is the file AdobeRGB1998.icc which, according to iccgamut, has "ICC
v4" header, which is unsupported. Such icc file is distributed with colord
- I have it installed in /usr/share/color/icc/colord/AdobeRGB1998.icc on
Ubuntu 16.04. I thought it was good...
The unexpected thing is that colprof does not complain about the ICC header
version but just breaks with segmentation fault. It would be nicer to catch
this corner case and get a more informative error message. It took me a
while to understand where the issue was :)
Anyway, using AdobeRGB.icc taken from here
https://www.ludd.ltu.se/~torger/photography/files/AdobeRGB.icc
solved the issue.
I observe this behavior both with colprof v1.9.2 and v1.8.3.
Here is the full log of the error:

Hope this helps.
