If you press Ctrl-C during Python startup on Windows you may get interpreter crashes with different Python tracebacks displayed on the standard system error output stream.
Reproduced using:
- Windows 7 SP1 x64
- Python 3.3.3 (64-bit) as downloaded from 'http://www.python.org/download/releases/3.3.3' (but seen with different earlier Python versions as well).
- either a non-trivial Python script, one containing only a '#! python3' shabang line, or a completely empty one
- default site.py
To reproduce simply run the Python interpreter with a prepared Python script as input and press Ctrl-C immediately afterwards.
Possible results:
* Script finishes before your Ctrl-C kicks in.
* You get a clean KeyboardInterrupt traceback and the script exits.
* You get a KeyboardInterrupt traceback and the interpreter process crashes.
I'm attaching more detailed information on specific crash instances.
