[issue3242] Segfault in PyFile_SoftSpace/PyEval_EvalFrameEx with sys.stdout reassigned

[Amaury Forgeot d'Arc]

I reproduced the problem on windows, and it is indeed a problem with the
"print" statement, when the write() method reassigns sys.stdout: the
code calls PyFile_WriteString(), then PyFile_SoftSpace on the same
object, which has been freed in your case.
A pair of INCREF/DECREF did the trick. See attached patch.
