Emacs crashes for me with or without gdb (and under lldb).

    Andrii> So I tried to use lldb.
    Andrii> Under lldb the crash is not occured on commit with 'ok = false'.

    Andrii> Also I came up with code to reproduce crash under 'emacs -Q' at least on

    Andrii> Here is the '~/emacs-crash.el' content:

    Andrii> (delete-frame)
    Andrii> (delete-frame)
    Andrii> (delete-frame)
    Andrii> (delete-frame)
    Andrii> (garbage-collect)

That doesnʼt crash for me with 'emacs -Q', but Iʼm not on 10.15.2 yet,
Iʼm still on 10.14

    Andrii> This code is start crashing on the commit

    Andrii> Though I can't use xTYPE commands under lldb please see attached lldb

Thatʼs very different from the call stack I see. Perhaps we have two
bugs?
