Comment 1 Halla Rempt 2012-11-04 08:59:03 UTC

It also happens when going from rgbu16 to rgbf16 -- and those have the same memory footprints.

Comment 2 Halla Rempt 2012-11-04 09:02:50 UTC

Hm, and memcheck crashes on this as well.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

I think this is an lcms issue as well. When I upgraded to the latest lcms from git master, the problem went away.
