I have just tested on Windows and all works to me. Terry, can you confirm that 
this issue is gone?

From Ned Deily's message.
haven't tried it recently on a Linux system

Output from a linux syste:

./python -m test  -ugui test_ttk_guionly test_ttk_guionly test_idle test_idle
[1/4] test_ttk_guionly
[2/4] test_ttk_guionly
[3/4] test_idle
[4/4] test_idle
All 4 tests OK.

So it confirms as a windows issue. Unfortunately, that's all I have to offer on 
this issue ATM.

[Ned Deily]

Ned Deily added the comment:

For what it's worth, I don't see the problem on OS X (haven't tried it recently 
on a Linux system), so it might be a Windows only issue. It's become clearer 
that some test combinations can only be safely run with the regrtest -j option 
to run them as separate subprocesses. I Does -m test -j2 -ugui 
test_ttk_guionly test_ttk_guionly help?

[issue20800] Cannot run gui tests twice.

[Terry J. Reedy]

New submission from Terry J. Reedy:

After the fix for #20567, running test_idle and then test_ttk_guionly works, 
but running either after itself does not. Example command and output, which is 
same running with installed 3.4.0rc1 (Feb 11) or fresh debug build.

During handling of the above exception, another exception occurred:

init.tcl *is* in 4/tcl8.6.1.0/library and 4/tcltk/tcl8.6/lib. I believe it is 
usually found in the latter.

This might be Windows only.

The Warning -- os.environ was modified by test_ttk_guionly looks suspicious.  
Does the patch for Issue20035 help?

The #20035 patch removes the warning but the rest is the same.

What happens if you add -v (verbose) ... -m test -v -ugui ... to find the 
failing tests?

[Terry J. Reedy]

Terry J. Reedy added the comment:

With 3.3 and the patch still applied, all 13 test methods fail with tracebacks 
that end with the _tkinter.create call, as above. For Idle, there are 3 
tracebacks for the 3 modules with gui tests.
