5.1-beta-rc seg fault on luaopen_io(L)

Title: 5.1-beta-rc seg fault on luaopen_io(L)

I downloaded and installed lua-5.1-beta-rc.tar.gz. When I try to open up the io library using "luaopen_io(L)" the application has a segmentation fault. The application does not seg fault when linked with 5.0.2.

The line that seems to be causing the error is in src/liolib.c:
  lua_replace(L, LUA_ENVIRONINDEX);

My main.c contains:
kbox: expected PASS found 139
    lua_State *L = lua_open();
    if (!L) {
      fprintf(stdout, "error:\tunable to initialize Lua VM\n");
      exit(2);
    } else if (!luaopen_base(L)) {             // opens the basic library
      fprintf(stdout, "error:\tunable to initialize Lua base library\n");
      exit(2);
    } else if (!luaopen_table(L)) {            // opens the table library
      fprintf(stdout, "error:\tunable to initialize Lua table library\n");
      exit(2);
    } else if (!luaopen_io(L)) {               // opens the I/O library
      fprintf(stdout, "error:\tunable to initialize Lua io library\n");
      exit(2);
    } else if (!luaopen_string(L)) {           // opens the string lib
      fprintf(stdout, "error:\tunable to initialize Lua string library\n");
      exit(2);
    }

I'm using gcc 4.0.0 on SunOS 5.8.

Thanks,
Mike
