Argh, sorry for the confusion, I found the answer to my question at 
http://www.lua.org/manual/5.1/manual.html#lua_tolstring

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,
Carsten
