The maximum setting of Lua's stack limit depends on the runtime stack
limit set by the OS. You can usually grow this by using the shell
command "ulimit -s <size-in-kbytes>".

The flag "-fsanitize=address" must generate code that uses a lot of
extra stack space. On my Debian 10 system I can run a program with the
C stack limit at 20000 without crashing. Compiled with
-fsanitize=address the crash happens below 4000. I did not change the
process stack limit, it's set to 8192 Kbytes.
