4284718fb631 Issue2297: Fix a stack overflow in Windows caused by -v and -vv. When python is invoked with -v or -vv under Windows, the process of importing the codec for sys.stderr causes a message to be written to stderr, which in turn causes the codec to be recursively imported. Sometimes the stack overflow exception is swallowed, other times it is not. The bug depends on the particular locale settings of the Windows machine.
