Gerhard, I just build the new version of lcms and ran LPROF against it without rebuilding it. I don't know what I was thinking as the first thing I should have done once the new version of lcms was installed is to rebuild LPROF just in case something changed like it had in fact done this time. I just rebuilt LPROF against the new version of lcms and it runs fine. Including not being able to reproduce the problem that Cory reported with the profile checker. So Cory's problem is not 1.15 specific. I will have to revert back to lcms 1.14 for a while since I will have to rebuild a number of other apps if I don't. But it is good to know that lcms 1.15 does not appear to have any problems.
