You didn't patch this function, but you probably had to.
Here's something for you to fix:

box.cfg{}
s = box.schema.space.create('test')
i = s:create_index('pk', {parts = {{1, 'integer', path = '[1]'}}})
s:insert{{-1}}
i:alter{parts = {{1, 'string', path = '[1]'}}} -- success
s:insert{{'a'}} -- crash
