Neil Schemenauer:
Okay. Perhaps I am missing something but would fixing it be as simple as adding another field to the tp_as_buffer struct?
/* references returned by the buffer functins are valid while * the object remains alive */ #define PyBuffer_FLAG_SAFE 1
That's completely different from what I had in mind, which was: (1) Keep a reference to the base object in the buffer object, and (2) Use the buffer API to fetch a fresh pointer from the base object each time it's needed. Is there some reason that still wouldn't be safe enough?
