So we likely are looking at a memory corruption bug in OSG
Yes. That looks very much like an OSG bug. And valgrind agrees.
The textures are perfectly valid. BTW: according to my checker we
don't have a single corrupted SGI image file in CVS.

I have to take this back. The code is rather ugly -- it reads more
data than are available, and valgrind complains about that. But after
that the line decoder breaks correctly. I don't see

Xnview reports no errors in cirrus.rgba, or with any of the textures.
Perhaps you have corrupted the clouds textures locally? Did you open them in

Textures/Sky/broken.rgba seems to be literally just that,
broken. Or rather, corrupted. As do scattered, few, and
cirrus. fg/osg (but not
plib) frequently crashes

Confirmed that osg seems to understand them, try it:
osgviewer --image cirrus.rgba
So the format is ok, the question is where's the bug? It would
certainly seem that it lies in the difference between these two
variants of SGI images. It's probably within OSG itself.
The other question is, what

ImageMagick does not think these corrupted (identify(1) should return
