[CuriousGeorgiy]

Steps to reproduce

os.execute('rm -rf *.snap *.xlog *.vylog 512')

local fiber = require('fiber')
local ffi = require('ffi')

box.cfg{memtx_use_mvcc_engine = true}

local s = box.schema.space.create('s')
s:create_index('pk')

s:replace{0}

local first_replace = fiber.new(function()
    box.atomic(function()
        s:delete{0}
    end)
end)
local second_replace = fiber.new(function()
    box.atomic(function()
        s:replace{0}
    end)
end)

first_replace:set_joinable(true)
second_replace:set_joinable(true)

first_replace:join()
second_replace:join()

os.exit()
