When running a moderately complicated calculation in FriCAS I get the
following abort:

I am used SBCL 1.1.5 to build FriCAS.
wspage@suse:~> sbcl --version
SBCL 1.1.15

Is there some way to dynamically change the memory allocation?
I tried changing the 'fricas' script
if [ "$*" = "-nosman" ] ; then
exec "$AXIOM/bin/AXIOMsys" -- --dynamic-space-size "4Gb"
exit 1
fi
to pass "dynamic-space-size" but this does not seem to have any effect.
Can I build FriCAS from SBCL to provide more memory by default?
Bill Page.
