insufficient memory

Six months later I've been able to find out the answer to my question.
The explanation is at the bottom of this page:

http://common-lisp.net/project/cmucl/doc/cmu-user/aliens.html

So basically there will never be any -dynamic-space-size that will
allow more room for external allocation.  This is predetermined by
CMUCL (or SBCL) and won't change, no matter what.

As far as I can tell there is no way around.  I suppose one should
just try to keep external allocation as small as possible and keep
large objects as Lisp objects (not as reference to aliens).
