Here with 2.7.5 on Windows (Vista):

Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import io, sys
>>> fd =, 'wb')
>>> fd.close()
>>> sys.stdout.write("now writing on stdout will cause a crash")

At this point Windows pops up a box saying "python.exe has stopped working".  I don't have a debug build available, and all I can find out is that it's a memory error in this line, somewhere in MS's C libraries:

and         dword ptr ds:[718DD7A0h],0 

So, ya, it's a crash ;-)
