bug#47244: 28.0.50; SIGSEGV in long-runnning Emacs

[Michael Welsh Duggan]

And, trapped!  Backtrace is included.  Maybe unfortunately, it isn't one
of the new easserts, but at least we now have a different backtrace.
Hopefully that will lead to new insights.  I will note that, in this
instance, the reproducer did not follow the same formula, as you can see
in the Lisp backtrace.
