New submission from STINNER Victor <victor.stin...@haypocalc.com>:
In Python 3.2, when you get a buffer from array.array('u'), "u" is used as
buffer format. The format is supposed to be a format from the struct module,
and "u" is an invalid struct format. "w" is used on wide mode.
I just upgraded the array module to use the new Unicode API (PEP 393). The
array now uses a Py_UCS4 buffer. I used "I" or "L" format depending on the size
of int and long C types.
It would be better to use a format for a Py_UCS4 string, but struct doesn't
support such type.
For Python 2.7 and 3.2, I don't know if it is really a bug or not.
