Setting sys.stdin to an invalid input stream under interactive mode causes interpreter run loop forever: Python 3.3a0 (default:22ae2b002865+, Mar 30 2011, 21:17:03) [GCC 4.4.4] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys [57804 refs] >>> sys.stdin = None [57809 refs] [57809 refs] [57809 refs] [57809 refs] [57809 refs] ...... Not only setting to None but also to any other invalid input stream could cause this. It's because in the beginning of PyRun_InteractiveOneFlags(), in order to get stdin encoding, the code tries to get sys.stdin and check if it's valid(not NULL, not None, has "encoding" attribute), if not, return -1 directly, then the loop in PyRun_InteractLoopFlags() continues and does the same thing. I think this should be fixed by using the Py_FileSystemDefaultEncoding instead when sys.stdin is invalid. |

I think that it is a duplicate of #8070. |
