Uh oh!
There was an error while loading. Please reload this page.
_PyTuple_Resize() did not validate newsize for non-empty tuples.
Raise SystemError for a negative size and MemoryError for a too-large size,
like PyTuple_New() already does for the empty-tuple path.
(cherry picked from commit c360884)
