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

["Henderson, Michael D" <michael.d.henderson@...>]

Title: Message

I just compared to the code that I used in 5.0.2 and now I'm confused. In 5.0.2 I didn't check the return codes of the functions, I just assumed that they always succeed (I basically use the example from PIL). For some reason I updated main.c for 5.1. So, please ignore the main.c I copied in the original message.

 

I changed the main.c code back to my 5.0.2 version.

 

    if (!L) {
      fprintf(stdout, "error:\tunable to initialize Lua VM\n");
      exit(2);
    }
    luaopen_base(L);             // opens the basic library
    luaopen_table(L);            // opens the table library
    luaopen_io(L);               // opens the I/O library
    luaopen_string(L);           // opens the string lib
    luaopen_math(L);             // opens the math lib

I compiled and linked with 5.0.2. It runs. I recompiled and relinked with 5.1-beta. It abended as noted below.

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);

I'm using gcc 4.0.0 on SunOS 5.8.
