At unpredictable times while editing c++ files, emacs will segfault.
I haven't been able to reproduce without lsp-mode, but with how
unpredictable this is I don't think that necessarily means much.
The problem exists with and without native compilation- this
report assumes without.

STEPS TO REPRODUCE:
- Let '~/minimal' contain the attached init file
- Start emacs with 'emacs --init-directory ~/minimal'
- Open a c++ file
- Edit it, taking care to type quickly and go back to edit within
   words. I can usually get a crash within 10 minutes, but I haven't
   been able to iterate enough to figure out exactly what is
   happening. It's always while typing though, I think in response
   to a keydown.

Attached is the init file I used to reproduce this, and the backtrace.
I had issues with the .gdbinit, which I will hopefully address when
I get back from vacation.
