The file causing failure was added in FriCAS 1.3.10, it is not present
in earlier versions.

You can use your own sbcl "executable" (that is shell script). Put
the following into a file called 'my_sbcl' (or whatever you prefer):
#!/bin/sh
exec sbcl --dynamic-space-size 4096 "$@"
and do 'chmod 755 my_sbcl'. After that you can use 'my_sbcl'
as your Lisp.

Actually, this is quite easy:
1) Dowwnload sbcl sources from www.sbcl.org
2) Unpack (untar) sources
3) cd to sbcl-x.y.z (where x.y.z is sbcl version)
4) sh make.sh --dynamic-space-size=8Gb --prefix=/path/to/install/directory
where /path/to/install/directory points to place where you want it
to live
5) sh install.sh

Good for you. 'sbcl' running out of memory during compliation is old
news. Some old versions had insane memory use (IIRC somebody tried
to give 200Gb to sbcl and it was still not enough), our 'configure'
refuses to build FriCAS with affected versions. I have built
FriCAS 1.3.10 using sbcl-2.3.9, so in last few version sbcl got
more memory hungry.

Something changed between sbcl-2.3.9 and sbcl-2.4.0. File added
to FriCAS 1.3.10, that is RSIMP.spad compiles fine using sbcl-2.3.9.
