Do you have different programs called "lua" or "sol" in your PATH
that are getting executed instead of the copy in the current
directory?
Or is this definitely a reproducible problem on your platform when the
argv[0] is any 3 character string?
(I don't have "." in my PATH, even at the end, to avoid issues running
the "wrong" version of a program when cd-ed to arbitrary directories.)
