Ok, but I might be wary of this. You can fetch the CVS version of
wxLua which has been upgraded to Lua 5.1.4.

If you use require("wx") then lua_close(L) is appropriate, however if
you use a wxLuaState then use wxlState.CloseLuaState(true); to have it
cleanup wxLua properly.

You can have many lua_States each with wxLua loaded with no problem.

Could you compile wxLua and Lua with debug symbols and run your
program in gdb? When the program crashes just type "bt" (for
backtrace) and post the results.
