I do use the latest version of gcl.
I tried to issue the broken parts manually but failed with setting the
source ../hol88_commandline
-bash: set_library_search_path
[`/home/srs/DEBs/hol88/hol88-2.02.19940316/Library`];;: No such file or

cat hol88_commandline
#set -x
#echo 'set_flag(`abort_when_fail`,true);;'\
    'loadf(library_pathname() ^ `/prettyp/PP_printer`);;'\
    'loadf(library_pathname() ^ `/prettyp/PP_parser`);;'\
    'PP_to_ML false `latex_type` ``;;'\
    'quit();;' | /home/srs/DEBs/hol88/hol88-2.02.19940316/hol

I managed to create a batch version, see attached maxima_commandline,
and got an rpctrace (not attached, too big) and a gdb backtrace
(maxima_gdb.txt). Seems like the bugs are in the memory protection
