Bug description:
Running python REPL under another program (strace ./build/python in my case), then pressing Ctrl-C on Linux results in an infinite stream of exception tracebacks.
Tested on Python 3.13 branch and main
During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/build/python/cpython/Lib/_pyrepl/readline.py", line 394, in multiline_input return
