[Lcms-user] Regression? Added a check on LUT consistency

[Richard H. <hug...@gm...>]

Since 9936ecf0745002cea8e46dc575079b4872e9af8c in lcms2 I'm getting a
failure on the colord self tests:

What the self test is trying to do is creating a proofing transform
with gamut check, so we can getting the coverage of one profile of
another, i.e. to approximate the gamut intersection. e.g.

profile_null = cmsCreateNULLProfileTHR (ctx);
transform = cmsCreateProofingTransformTHR (ctx,
  hnd1,
  TYPE_RGB_FLT,
  profile_null,
  TYPE_GRAY_FLT,
  hnd2,
  INTENT_ABSOLUTE_COLORIMETRIC,
  INTENT_ABSOLUTE_COLORIMETRIC,
  cmsFLAGS_GAMUTCHECK |
  cmsFLAGS_SOFTPROOFING);

Since 9936ecf0 the transform is coming back NULL. Am I doing something
broken, or is this indeed a regression?

Richard.
