I am not a JPEG 2000 expert. However, I am able to reproduce the
problem under Solaris and Linux. It is clearly an issue in Jasper
since assertions should be left for cases which should never happen.

something to do with color management profiles, which was perhaps not
completely finished with development before the Jasper maintainer
stopped making releases.
FYI, Debian has removed Japer from its latest releases due to not
being officially maintained for over 10 years and the Debian Jasper
maintainer quitting. This means that it will be dropped from Ubuntu,
Mint, and other Linux systems derived from Debian.
GraphicsMagick does not yet offer support for OpenJPEG, which is the
only free JPEG 2000 library with recent releases.
