I've tested this on Emacs 30 on mac OS 14.5, and the bug is still
present.  I now get this backtrace, however:

Debugger entered--Lisp error: (void-function eshell-set-exit-info)
  eshell-set-exit-info(0 t)
  #f(compiled-function () #<bytecode 0x1cf599f366a88a85>)()
  eshell-sentinel(#<process grep> "finished\n")

Copying in Jim Porter, in case he has any ideas.
