I've played around with the docker containers a bit, but couldn't find anything 
interesting.  Given the error message, I'm 99% sure it's a kernel bug (which 
gets triggered when raise(SIGABRT) is called), so maybe it would be best to 
report this to the Linux kernel folks?
BTW, a more minimal command to reproduce it is
# /checkout/src/emacs -batch -Q -module-assertions -eval "(progn (setq 
attempt-orderly-shutdown-on-fatal-signal nil) (require 'mod-test 
\"/checkout/test/src/emacs-module-resources/mod-test\") 
(mod-test-invalid-finalizer) (garbage-collect))"
