Subject: [Tarantool-patches] [PATCH luajit] test: adapt test checking reversed function
Date: Thu, 30 Sep 2021 14:43:37 +0300	[thread overview]
Message-ID: <20210930114337.1575120-1-m.kokryashkin@tarantool.org> (raw)

The first fiber in Tarantool has only 512Kb of the stack which is not enough to
handle such a deep call chain.
The test is adapted to Tarantool by decreasing the string length.

Closes tarantool/tarantool#5782
