[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

As far as the rule of disallowing shape changes while a buffer is exported, I actually think that's a more sane approach as well. However, I've been burned enough times by going "nobody would be insane enough to rely on that, would they?" that I'm seriously reluctant to impose additional backwards incompatible rules on a published spec when it isn't *too* difficult to adjust the infrastructure to better handle the existing complexity.
