bug#30800: 26.0.91; unknown crash on macos |

I was able to get more information, though this trace is different.
I believe this crash has to do with child frames as my repro involves
using flycheck-posframe. For what it's worth, my repro is as follows:
1. Start emacs w/ my config
2. Open a typescript file
3. Cause a flycheck error by deleting a character from an identifier
4. Put the point on the error and move it off several times to see the
child frame w/ the error appear and disappear
5. Click away from emacs
6. Click back in
7. split-window-right
8. Sometimes this is enough to crash it, sometimes I hit a binding
that uses find-file-existing to open my init.el and that crashes it.
On emacs-26 (e4b73abd38)
I'll leave the debugger running in case anyone has any questions about
its state.
Here is the crash:
