There are a lot of good answers here, but no one has yet touched on the Lua angle.

Lua is generally pretty well behaved, but it is still possible for it to cause memory corruption or crashing if e.g. the Lua stack overflows or underflows, or bad bytecode is executed.

One easy thing you can do that will detect many such errors is to define the lua_assert macro in luaconf.h. Defining this (to e.g. standard C's assert) will enable a variety of sanity checks inside the Lua core.
