Another bug, truncated traceback since the top was the same:

test_heading_callback

STINNER Victor added the comment:

Ah! I captured the traceback of a first bug using the command:

PCbuild\amd64\python_d.exe -m test -R 3:3 -u all -v --timeout=30 -r -F 
test_ttk_guionly

Output:

[issue31068] test_ttk_guionly hangs on AMD64 Windows8.1 Refleaks 2.7

[STINNER Victor]

STINNER Victor added the comment:

I'm trying to reproduce the bug using the following command run in a Command 
Prompt:

PCbuild\amd64\python_d.exe -m test -r -u all -R 3:3 -F -v --timeout=30 
test_ttk_guionly

Note: I'm using https://github.com/python/cpython/pull/3019 to get --timeout 
feature.

Once (when I wasn't using --timeout=30), I saw 
test_ttk.test_widgets.TreeviewTest.test_tag_bind() stuck! But it only saw this 
bug twice in 1 hour of intensive tests, and so I'm not sure that it exists.

Since I unable to easily reproduce the bug, it's hard to collect more 
information about the program state when the bug occurs.
