A problem internal to GDB has been detected,
further debugging may prove unreliable.
When I start gdb from the command line and attach emacs there I get this:

To run gdb on macOS you need to follow instructions like the following: https://gist.github.com/gravitylow/fb595186ce6068537a6e9da6d8b5b96d
Thank you Alan,
I actually had found a similar page and followed similar instruction to get a weird error message: Unkown error = -2,147,414,007
I'm not online at the time of this writing so I can't investigate more but I will.

otherwise it’s simply not allowed to attach to another process. (I’ve
not tried these specific instructions.)
lldb should already be signed so will work, but you’ll miss out on
some gdb specific settings in the emacs source.
