Can you give more details? I could not reproduce that behavior.

One of the main uses of require is to search for modules. So it cannot
leave the path unmodified. There is one function that leaves all
untouched: loadfile. Actually, you can use it together with require (but
don't have to):

  package.preload["modname"] = loadfile("/whole/path/myfile.lua")
