This is from Includes/cpython/longintrepr.pxd in Cython 0.28.4, which

This is from the same file in Cython 0.29~rc2-1, which does trigger
the above error:

     ctypedef class __builtin__.py_long [object PyLongObject]:
         cdef digit* ob_digit

This was done in https://github.com/cython/cython/commit/4bd2c9b85ac2d85fe40a56296dcc86f271313c11

Particularly interesting is the change in tests/run/longintrepr.pyx:

  ret = _PyLong_New(index + 1)
- (<PyLongObject*>ret).ob_digit[index] = low
+ ret.ob_digit[index] = low


There is exactly one use of PyLongObject, on line 211:

     cdef const digit* D = (<PyLongObject*>x).ob_digit

Would changing to:

    cdef const digit* D = x.ob_digit

do?
