It fails on my system too (cd-iccdump prints ne_SU instead of en_US):

Just found out that it is caused by liblcms2-2 (2.8-2).
After downgrading it to the version in stretch (2.7-1), everything is
printed normally.

Control: reassign -1 liblcms2-2 2.8-2
Control: retitle -1 liblcms2-2 causes cd-iccdump to output incorrect locale names
Control: affects -1 + colord diffoscope

Hello liblcms2-2 maintainer, just reassigning the bug described below. You can reproduce it with $ cd-iccdump <some test file> 

e.g. from the diffoscope source tree:

$ cd-iccdump tests/data/test1.icc  | grep 'en_US\|ne_SU'
  ne_SU:	sRGB [24 bytes]
[.. etc ..]

Seems endian-related.

I think I found the cause. cmsMLUtranslationsCodes() now uses the new
strFrom16() function. The problem is that strFrom16() does not work
under little-endian systems.

  static
  cmsUInt16Number strTo16(const char str[3])
  {
      cmsUInt16Number n = ((cmsUInt16Number) str[0] << 8) | str[1];
  
      return n;  // Always big endian in this case
  }

  static
  void strFrom16(char str[3], cmsUInt16Number n)
  {
      // Assiming this would be aligned
      union {
  
         cmsUInt16Number n;
         char str[2];
         
      } c;
  
      c.n = n;  // Always big endian in this case
  
      str[0] = c.str[0]; str[1] = c.str[1]; str[2] = 0;
  
  }

On a little-endian system strFrom16() wrongly swaps the byte order (even
though the comment says something different). You can easily test this
with the attached minimal test case (see test.c).

I think the easiest solution is the use a machine byte order independent
calculation like in strTo16(). See attached patch.

Did this get sent upstream? :)  We are seeing other distributions
hitting the same issue:

The bug report has a "Forwarded to" header and the patch has a "Bug:"
tag following DEP3: https://github.com/mm2/Little-CMS/issues/110
So, yes, this was sent upstream. Upstream chose a different way forward
which albeit didn't work.
