The three times that I caugth the crash with the debugger mini-echo [1]
was in the Elisp backtrace. Maybe lsp-mode does something that upsets
the garbage collector and it surfaces when mini-echo executes. Just now
tried for some minutes with mini-echo active and without lsp-mode and no
crash, but maybe I was unlucky. lsp-mode is heavy on GC and it is
difficult to replicate that.

As for the core dump, I have two, but I'm not sure if they contain
sensitive info. Usually the crash takes a few minutes of work to happen.
I can execute Emacs under gdb on a controlled environment and then
answer your requests, no problem with having it open for several days.
Or send you the core dump, if it is more useful.
