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.
