From 5f8a9e6a028e9528567682cb0a92addb23032787 Mon Sep 17 00:00:00 2001 From: Ryan Moeller Date: Tue, 22 Sep 2020 19:03:11 -0400 Subject: FreeBSD: Reduce stack usage of Lua Use the same reduced buffer size for lauxlib that is used on Linux. Fixes panic on HEAD in lua gsub test designed to exhaust stack space. With this we can remove the special case to reserve more stack space on FreeBSD.
