After opening a tkinter window, command line interpreter crashes after getting a command from the clipboard ending with a comment

Bug report

Bug description:

I use Python in Windows 1O.
If I enter the command
w = tkinter.Tk()
in the command line interpreter, the interpreter starts behaving strangely.
Commands entered directly from the keyboard
and commands pasted from the clipboard and not ending with a comment,
it continues to process as expected.
However, whenever I paste from the clipboard a command that ends with a line comment,
the interpreter crashes, and with it the entire command line window.
However, the window opened in tkinter remains open
and closes only when its close button is pressed.

CPython versions tested on:

3.10, 3.11, 3.12

Operating systems tested on:

Windows

I cannot repeat either with freshly updated and compiled main or with installed 3.12.2

f:\dev\3x>python
Running Debug|x64 interpreter...
Python 3.13.0a4+ (heads/main:0656509033, Mar  3 2024, 11:43:20) [MSC v.1932 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> w = tkinter.Tk()
>>> a = 3 # commetn
>>> a = 3 # commetn <pasted> behaves normally
>>> quit() # Tk window closes

When I repeated the above with 3.12.2 to the 'w' line and then pasted in the above, I got several SyntaxErrors, and the tkinter disappeared, but no crash. Interpreter continued normally. I repeated again from beginning pasting legal code and all was well. Please copy and paste exactly what you did, though I suspect there is an idiosyncratic problem with your system.

I apologize for the long pause, but in the confusion of the beginning of the semester, your email got lost somewhere and I just found it now while cleaning out my mail. After reading your reply, I tried the program on several other computers, and indeed, and indeed, the problem I reported, for reasons unknown to me, was only occurring on one. If I had noticed it earlier, I would not have reported anything. I'm sorry to have bothered Have a nice day Rudolf Pecinovsky Dne 2024-03-03 18:00, Terry Jan Reedy napsal:
