Well, more specifically, it's designed to have debugging stuff
passed straight through it from the compiler to the object file,
rather than generating debugging info for the _assembly_ level.

Hopefully when NASM finally gets round to this (don't hold your
breath, people, I'm afraid) it will have options to do both.
_Hopefully_.

Er, try reading the help a little more closely. You do need some
special syntax (an asterisk), but it can be done:

  (gdb) help break
  Set breakpoint at specified line or function.
  Argument may be line number, function name, or "*" and an address.

So you just do `break *0x80123ab' and it works fine. I've been doing
it a lot for the last month, as it happens. With NASM, but the
principle's the same.
