    I forgot to say what happens when it's rerun again and again. First it leaves only 2 files behind:
    -r--r--r-- 1 clock users 120000 Jan 6 09:12 moss.pix
    -rw-r--r-- 1 clock users 44400 Jan 6 09:12 moss.pix.1
    After first re-run:
    -r--r--r-- 1 clock users 120000 Jan 6 09:12 moss.pix
    -r--r--r-- 1 clock users 120000 Jan 6 09:12 moss.pix.1
    -rw-r--r-- 1 clock users 44400 Jan 6 09:12 moss.pix.2
    After second one:
    -r--r--r-- 1 clock users 120000 Jan 6 09:12 moss.pix
    -r--r--r-- 1 clock users 120000 Jan 6 09:12 moss.pix.1
    -r--r--r-- 1 clock users 120000 Jan 6 09:13 moss.pix.2
    -rw-r--r-- 1 clock users 44400 Jan 6 09:13 moss.pix.3

    This way the complete sequence can be done. When I continue according to the animation guide, fbanim shows an animation, where the picture is broken so that the lower say 2/5 are different
    than the upper 3/5. The first 3 frames have the upper part of the picture black. The lower part seems to stay the same and the upper part shows the rotating body. There is also a strip of
    obvious garbage, about 2 pixels high, at the bottom of the picture. The garbage consists of alternating black-red-black-green-black-blue pixels or something like that.

    This is the moss.log after the first run of the moss.rt:

    My CPU and memory seem to be OK (never had a problem). My disk has 4 bad sectors which pop up every time I check the disk. The system already hanged once probably because of this. To make sure the
    bad sectors didn't corrupt brl-cad, I downloaded the source and recompiled and reinstalled and ran ldconfig -R and then tried again before reporting the bug.

    7.8.4 does the same. However it produces an empty runt file:
    clock@kestrel:~/creat/ronja/trunk/3d$ ls -la *pix*
    -r--r--r-- 1 clock users 120000 Jan 6 10:24 moss.pix
    -rw-r--r-- 1 clock users 0 Jan 6 10:24 moss.pix.1
    After rerun:
    clock@kestrel:~/creat/ronja/trunk/3d$ ls -la *pix*
    -r--r--r-- 1 clock users 120000 Jan 6 10:24 moss.pix
    -r--r--r-- 1 clock users 120000 Jan 6 10:26 moss.pix.1
    -rw-r--r-- 1 clock users 0 Jan 6 10:26 moss.pix.2

    The stack trace is different:
