[Tarantool-patches] [PATCH luajit 0/2] Snapshot restore with stack overflow

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

This patchset fixes the issue with stackoverflow during the snapshot
restoration. The first patch solves the problem in the incorrect way,
since it leads to the uninitalized read. The second patch fixes the
issue correctly.
