[Tarantool-patches] [PATCH v10 4/4] test: add replication/applier-rollback
Cyrill Gorcunov

Fri Feb 14 17:03:39 MSK 2020
In the test force error injection ERRINJ_REPLICA_TXN_WRITE
to happen which will initiate applier transaction rollback.
Without the fix it will cause SIGSEGV due to lack of error
propagation.
