Summary: PyString_AsString() segfaults when passed a unicode string
Initial Comment:
If you pass a PyObject representation the unicode
string u'\xc4'
to PyString_AsString() then Python (2.3.4, 2.4.0) segfault.
Famous last words of Python 2.4:
Exception exceptions.UnicodeEncodeError:
<exceptions.UnicodeEncodeError instance at 0xf6f75e8c>
in 'garbage collection' ignored
Fatal Python error: unexpected exception during garbage
collection
Famous last words of Python 2.4 (debug build):
XXX undetected error
Traceback (most recent call last):
File "test.py", line 4, in ?
print S.split(u'\xc4')
UnicodeEncodeError: 'ascii' codec can't encode
character u'\xe4' in position 0: ordinal not in range(128)

This bug has been reported first on the zope-dev list.
I confirmed
that this error does not only occur in Zope but also in
a Python-only
environment.

For the record, this appeared to be due to an extension
module doing
PyString_AsString(name)[0]
when name was a Unicode string containing a "high-bit"
character. PyString_AsString(name) legitimately returned
NULL, and bad stuff followed.

I can't reproduce this:
>>> ick = u'\xc4'
>>> import struct
>>> struct.pack(ick)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
UnicodeEncodeError: 'ascii' codec can't encode character
u'\xc4' in position 0: ordinal not in range(128)
>>> struct.pack(u'i', 1)
'\x01\x00\x00\x00'
The code that provked this in Zope is buggy.,

Please attach a test case that shows the failure. I can't
reproduce it here with the information you've given.

This error not only happens with u'\xc4', it happens with
*any* string
containing a character >0x7f.
