New submission from R. David Murray:
I came across this by making a mistake, but it shouldn't crash:
rdmurray@hey:~/python/p32>touch temp
rdmurray@hey:~/python/p32>./python
Python 3.2.3+ (3.2:e6952acd5a55+, Feb 2 2013, 15:04:21)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from email import message_from_binary_file as mb
>>> m = mb(open('temp'))
python: ./Modules/_io/textio.c:1454: textiowrapper_read_chunk: Assertion
`((((((PyObject*)(input_chunk))->ob_type))->tp_flags & ((1L<<27))) != 0)'
failed.
zsh: abort ./python
This is a regression relative to 3.2.3:
Python 3.2.3 (default, Sep 16 2012, 16:35:39)
