I gather you're running the Lua interpreter via exec (or its variants) from
bash...

(BTW, are you aware of Lua Bash: http://freshmeat.net/projects/luabash/ ?)

Your fix is correct but I think you missunderstand the requirements on argv:
it's an array with argc+1 positions, the last one being NULL. So, you need
to malloc argc+1 positions for argv and set the last one to NULL before
exec'ing an external program.

Here are two references I found:
