[New-bugs-announce] [issue8113] PyUnicode_AsUnicode doesn't check for NULL pointer

[Lorenz Quack]

New submission from Lorenz Quack <don at amberfisharts.com>:

The C-API function "PyUnicode_AsUnicode(PyObject *unicode)" does not check the argument for NULL pointers. 
It passes it directly to the macro "PyUnicode_Check(op)" which then crashes when trying to access "Py_TYPE(op)".

I marked this as Python 2.7 because I checked this on trunk but I assume that this bug is present in all versions.

The attached patch fixes this issue.
