Content
There was a bug in copy_absolute(): if _Py_wgetcwd() failed, the result was undefined (depending of the content of "path" buffer). Especially, absolutize() calls copy_absolute() with a buffer allocated on the stack: the content of this buffer depends on the undefined content of the stack. Fixed in Python 3.2 (r85309+r85311), 2.7 (r85312) and 3.1 (r85313). copy_absolute() is used (by calculate_path()) to fill sys.path.
