Ah, I missed the "you have defined a buffer yourself" part.

So what seems to be happening is that there's another symbol also 
called "buffer" in glibc:

 (gdb) info symbol buffer
 buffer in section .bss of /lib64/libc.so.6

and gdb is picking that symbol instead of yours.

I can reproduce this if I compile a small program without debug info,
but with debug info (-g), it works as you'd expect.

I don't think we have syntax to disambiguate this, like
'libc.so.6'::buffer' vs 'program'::buffer, or program#buffer some
such, unfortunately.

Thanks,
