Comment (by tomio-arisaka):

 I think SBCL @2.2.9 port has two issues:

 (1) I guess that **sbcl-2.2.9-x86-64-darwin-binary.tar.bz2** was built on
 Monterey.

 {{{
 $ otool -L ./sbcl-2.2.9-x86-64-darwin/src/runtime/sbcl
 ./sbcl-2.2.9-x86-64-darwin/src/runtime/sbcl:
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1311.100.3)
 }}}

 So it is not compatible with earlier versions of macOS (earlier than
 10.12).

 {{{
 $ sw_vers
 ProductName:    Mac OS X
 ProductVersion: 10.11.6
 BuildVersion:   15G22010

 $ ./sbcl-2.2.9-x86-64-darwin/src/runtime/sbcl --core
 ./sbcl-2.2.9-x86-64-darwin/output/sbcl.core --disable-debugger --sysinit
 /dev/null --userinit /dev/null
 Segmentation fault: 11
 }}}
 Because earlier versions of macOS don't support {{{CLOCK_REALTIME}}}.

 (2) Earlier versions of clang don't know {{{__builtin_cpu_init}}}.\\

 This issue has been introduced since SBCL-2.2.6 due to including sb-simd.

 {{{

 :info:build avx2.c:2:3: error: use of unknown builtin '__builtin_cpu_init'

 :info:build   __builtin_cpu_init();

 }}}
