[Tarantool-patches] [PATCH v1 1/1] schema: remove assert on wrong insert into _priv
imeevma at tarantool.org

Mon Sep 6 11:11:45 MSK 2021
Prior to this patch, an assertion was throwed if a tuple with an
incorrect id was inserted into the _priv system space. This bug
appeared only in the debug build.
Closes #6295
