сегментации У меня есть странная проблема, когда я бегу питона оболочки:интерпретатор Python

$ python3 

Python 3.4.2 (default, Oct 8 2014, 10:45:20) 
[GCC 4.9.1] on linux 
Type "help", "copyright", "credits" or "license" for more information. 
>>> print('Hello') # Error appears for any command in shell 

[1] 9021 segmentation fault python3

Но когда я бегу python3 hello.py это работает.

Я уже пробовал python2.7, python3.4 и python3.5 и получил ту же ошибку.

OS Debian 8.4

Update 1

выход journalctl:

Update 2

Проблема еще не решена, но я обнаружил, что он работает правильно, если я запускаю его как другой пользователь. Я уже пытался удалить .cache и некоторые каталоги, связанные с python (.jupyter, .ipython), но это не дает результата.

Update 3

Я добавляю что-то близко один раз, проблема заключалась в том, что для какой-то оккультной причины некоторые .pyc-файлы в/usr/lib/были повреждены. Их устранение устранило проблему. – polku

Я сделал 'cd/usr/lib && sudo find. -name "* .pyc" -exec rm -rf {} \; 'он удаляет все * .pyc-файлы, но это не решает проблему. –

Вы проверяли переменные оболочки $ PYTHONPATH и $ PYTHONSTARTUP? возможно, они указывают на некоторые диски с противным * .pyc? – claperius

Итак, после некоторой отладки (хотя комментарии теперь больше походят на чат, они могут быть полезны в качестве примера сеанса отладки) было обнаружено, что segfault произошел из-за некоторой проблемы с настройкой readline, а именно для конкретных пользователей ~/.inputrc (и я бы сказал, что это, вероятно, ошибка чтения, потому что независимо от конфигурации, она не должна segfault).

Это показывает, насколько сложным и хрупким наше программное обеспечение, поскольку на первый взгляд не очевидно, что python может свернуть этот путь из-за сломанного файла конфигурации для библиотеки, которую не многие даже помнят о использовании python (если они даже помнят, что она существует).

Ошибка сегментации может иметь много причин.

Например:

Низкая память
Неисправный Ram памяти
