[New-bugs-announce] [issue29219] TracebackException(capture_locals=True) may fail with RecursionError

[Ilya Kulakov]

New submission from Ilya Kulakov:

I'm using Python 3.5.2 to be precise. I have code that is roughly equivalent to:

    import sys
    import traceback

    def handle_exception(exc_type, exc_value, exc_traceback):
        traceback.TracebackException(exc_type, exc_value, exc_traceback, capture_locals=True)

    sys.excepthook = handle_exception

For one of the clients the following error happened:

Traceback (most recent call last):
