Argh, sorry for the confusion, I found the answer to my question at
The problem was that for debugging something else, I did a call to
lua_tostring(L, -1); after the lua_pushinteger(L, 48); and then
according to the documentation: "If the value is a number, then
lua_tolstring also changes the actual value in the stack to a string."
So I was able to fix my problem by just removing the call to
lua_tostring() from my code.
However, I'm wondering why lua_tostring() behaves in this (somewhat
surprising) manner? This makes it different from all the other lua_to*()
functions, and I wonder why this is so??
Thanks, and best regards,
