[New-bugs-announce] [issue19578] del list[a:b:c] doesn't handle correctly list_resize() failure

[STINNER Victor]

New submission from STINNER Victor:

"del list[start:stop:step]" instruction doesn't handle list_resize() failure when step != 1.

Attached patch notifies the caller that list_resize() fails. On case of failure, the list is modified (items are deleted), it's just that list buffer could be smaller (it wastes memory).

See also issue #19568 which is similar for bytearray.
