just a quick question, does anyone know if its possible to set a break/watchpoint in gdb when a register points to a certain location?
i own the gdb manual, and have been playing in it for a bit and just cant seem to figure it out, is it possible?

I don't believe that could be done at all, the machine would have to
stop whenever it mov'd a value to the register so the debugger could
examine it. I don't think that's possible on Intel machines, anyway.

No, you can't (x86 at least).
What you can do is to watch the contents of the registers constantly and then manually stop your program.
