Comment (by snowflake):

 Running the bootstrap sbcl with the `run-sbcl.sh` script without any
 arguments, within 30 seconds the memory usage was 30GB. No prompt was
 displayed. I had to `killall sbcl -ABRT` to terminate the process or at
 least to get it into the lisp debugger.

 Viewing https://ports.macports.org/port/sbcl shows that at least 4
 successful installations of sbcl on Monterery exist, 3 on M1 and 1 on
 x86_64. So I wonder what is different about my system. It is running the
 latest Monterey beta as of 3 days ago on x86_64.

 There is no problem with building sbcl when running Big Sur here on
 x86_64.

 I notice there is another ticket #63752 on M1 processor with the reverse
 problem: unable to assign memory
