You've just found one. Me.
Seriously, you need GhostScript 2.6.1 with the following
modification to gdevgif.c:
/* #define TABLE_SIZE 5123 /* this is max for 12-bit codes */
#define TABLE_SIZE 5119 /* this is max for 12-bit codes (and prime) */
5123 is nice, but not prime, and this will in certain
circumstances produce an infinite CPU-consuming loop.
Second, uncomment the "30000 VM?" test in the PS files.
Third you will need the ps-to-gif script (a one-liner in the
shell given the right gs) and the landscape.ps which is available
together with the already converted (gif) files in
Note that a newer version of GhostScript won't do, since they
removed the GIF driver in subsequent versions to 2.6.1 (you
probably know why...).
However, newer versions of ghostscript have no problem creating ppm
files (if you compile w/ ppm driver), and you can use them along with
'pstogif' to generate GIF files. 'pstogif' is just a perl script that
runs gs to generate ppm, then pnmcrop, ppmquant and ppmtogif (from the
netpbm package). Also, 'convert' in the ImageMagick package will work
as well, and does something similar (i.e. I think you still need
ghostscript with ppm). I don't normally use 'convert' for PostScript to
GIF conversion though, since I've found it to be a lot slower than
I don't remember where I got 'pstogif' (maybe the CTAN archive?), so
here it is (albeit with my change to use a FIFO to speed things up a
