Modifying field of local table via c-Api

[Jörg Walter <joerg-walter@...>]

 Here is my approach for modifying local table1.entry1:

lua_getlocal(ls, &debug_info, targetIndex);
lua_getfield(ls, -1, "entry1");
lua_pushstring(ls, "newVal");
lua_setfield(ls, -2, "entry1"); // CRASH

It doesn't work. Any objections?

Cheers, Jörg
