I have the complete set of binary files from the BIOS tree, all 
together in "/" where SYSLINUX is installed (CWD).

Yes, there are several Lua-related modules, including vesa.c32. If 
this information is relevant, I might try to add it to the wiki by 
the time 6.03 stable gets out.

What I do not know is whether this "luaL_checklstring" problem is 
related to the Lua code in Syslinux (based on Lua v.5.2.3) with 
potential influence on additional modules / scripts, or instead is 
only related to vesa.c32 in particular. Perhaps reviewing this matter 
could potentially help with other Lua-related modules / code in 
Syslinux.

FWIW, searching for "luaL_checklstring" throughout the Syslinux 
source code, I can see it is present in several modules. It is also 
mentioned in "./com32/lua/doc/manual.html".

Perhaps Ferenc Wagner (Feri) might have something to add (for 
instance, http://www.syslinux.org/archives/2014-May/022067.html ).

TIA,
Ady.
