proposed fix for luac double free
Description of problem:
luac crashes with a double free when building lsyncd on f36 on armv7hl.
Strangely, it builds fine on f37 and on other f36 arches.
Version-Release number of selected component (if applicable):
lua-5.4.4-1.fc36
How reproducible:
always
Steps to Reproduce:
1. fedpkg clone lsyncd
2. fedpkg switch-branch f36
3. fedpkg scratch-build
Actual results:
https://koji.fedoraproject.org/koji/taskinfo?taskID=90077485

--- Comment #2 from Charles R. Anderson <cra(a)fea.st> ---
Can you please apply https://src.fedoraproject.org/rpms/lua/pull-request/7 and
backport to F36 so I can solve the FTBFS of lsyncd?
Thank you.
