New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:
The tp_clear handler of OrderedDict can set an exception when fail to allocate a nodes cache for an empty dict. An exception in tp_clear is not expected and caused a crash in the garbage collector. In the master branch it will cause just writing a traceback to stderr (see issue33622), but in any case it would be better to handle the failure locally in OrderedDict. Perhaps the cache for an empty dict is not needed.
