New changeset 439427ffbba1 by Benjamin Peterson in branch 'default':
merge 3.6 (#28417)
https://hg.python.org/cpytho
New submission from Xiang Zhang:
vargs2 could be va_end()ed twice in PyUnicode_FromFormatV when format contains
non-ascii characters. Once va_end()ed, vargs2 is undefined. So this could lead
to undefined behaviour.
