Yes, I tried this, but It did not have any impact on my problem. But just in the
moment I seem to have found a solution: I do not use lua_dostring(<function call>) 
anymore, but use lua_callfunction(lua_getglobal(<function name>)) after pushing the
parameters. 
I recognized, that dostring always claims new memory, when it is called with a new
string, in my case, when a parameter in the function call changed.
