On macOS 10.13.5 (the latest available) with ActiveTcl 8.6.7 (the latest available), I'm building Python from latest master (to be 3.8.0).  I'm consistently having IDLE crash almost immediately, just by opening any file for editing.  The crash results in the following error:

$ root/bin/python3 -m idlelib
objc[50759]: Invalid or prematurely-freed autorelease pool 0x7fb74091f050.
[1]    50759 abort      root/bin/python3 -m idlelib

In issue34120, @vtudorache reported a similar issue (also on macOS).

With Python 3.7.0 from python.org, everything works fine.

Strangely, replacing ActiveTcl with version 8.5.18.0 resolves this issue.

I'm not sure whether this is specific to IDLE; I'll try to provide a minimal way to reproduce.
