New submission from Masaya Suzuki:
Python 2.7.3 crushes when the following code is run without any library, which
means run python with -S option:
class Test:
pass
unicode(Test())
In the course of the interpreter tries to find the "__unicode__" attribute in a
class, it uses a cached python string of "__unicode__". The reason of this
crush is that the cached value is used before initialized. It is initialized
only when trying to find the one of a new-style class, so the interpreter will
crush if one uses only classic classes.
The attached patch will fix this issue by initializing a cached value before it
is used.
Thanks.
