A somewhat minimal reproducer for one of the reported crashes (also with
vanilla 21.4.19) is this in init.el:

  (require 'un-define)
  (set-default-coding-systems 'utf-8)
  (set-coding-priority-list '(utf-8))
  (set-coding-category-system 'utf-8 'utf-8)

...LANG=en_US.UTF-8 and XEmacs built with:

  export CFLAGS="-O2 -g -fstack-protector"
  ./configure --pdump --with-mule --without-wnn

And to trigger the crash, M-x manual-entry RET netstat RET

Installation and gdb and lisp backtraces for the crash attached.
