What you are seeing is a bug in psraster.c.  It keeps creating string
objects and not reclaiming VMemory.  For big images it finally runs out
of VM.  Here is a patch that works.

change line 194 to
______________________________________________________________________
fprintf( outfile, "{restore save GetImageRow}  save 6 1 roll image\n");
----------------------------------------------------------------------
VM will now be restored every time that image calls GetImageRow.

Would some kind soul please rewrite this program to not do
run-length encoding?  Max compression is 2.  Average execution
time increase is ~10.

Bye.
