I regularly build Lua 5.3 with TCC (mainly because of ultra small executable of only 64K after UPX compression). With v5.4 however I get into the stack issues I have reported that crash the tests. The same happens with MSVC (2013) unless the -Ox option is used. There is no optimization option (as was suggested) with TCC to overcome this problem. (And, IMHO a release should compile and run correctly with the default compiler option, not requiring any extra switches.)
So, for me at least, Lua v5.4 with TCC is no longer possible.

Subject: Re: Lua 5.4.0 (rc3) now available: compilation tests with gcc / TinyCC

works with
Centos 6.10 : gcc version 7.3.1 20180303 (Red Hat 7.3.1-5)
Debian 9 stretch : gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1)

Thanks for the report.

Have you any interest testing with TinyCC under Windos ?

We are interested in building Lua in as many combinations of OS and
compilers as possible. If you can do this and report here, it'd be
great. Thanks.
