I see Lua is defining a global called EXTRA_STACK which is set to 5. I also see that Lua always allocated EXTRA_STACK more elements than the actual stack size. My question, assuming my code violates the C API and uses these 5 extra elements (I don't really want to do it but wonder what will happen if something will use it because of a bug for example). Am I risking any crashes or invalid memory write/read. Valgrind do not warn about it of course, but I wonder if Lua might try to use this memory at some point and will not found what it is assuming to find there (because it was overwritten)

Thanks in advance
