New submission from Thomas Heller <[EMAIL PROTECTED]>:
IIUC, the bytes object should be immutable (in contrast to bytearray).
But PyObject_FromWriteBuffer() does not fail.
It seems that the attached patch fixes it; however there are lots of
failures in the testsuite with the patch - even 'memoryview(b"abcd")' fails.
