--- Comment #13 from John David Anglin <danglin at gcc dot gnu.org> ---
If I compile the trivial main program

int main() { return 0 }

with "gcc -o main -Wl,-z,relro main.c" and run main using gdb with
a break at _start

address@hidden:~/ffmpeg$ gdb main

(gdb) break _start
Breakpoint 1 at 0x10350
(gdb) r
Starting program: /home/dave/ffmpeg/main 

Breakpoint 1, 0x00010350 in _start ()

I get a bunch of inequivalent alias messages on the console:

mx3210 login: INEQUIVALENT ALIASES 0x10000 and 0x11000 in file main
INEQUIVALENT ALIASES 0x10000 and 0x11000 in file main

INEQUIVALENT ALIASES 0x10000 and 0x11000 in file main
INEQUIVALENT ALIASES 0x10000 and 0x11000 in file main
...

This doesn't happen without "-Wl,-z,relro".
