Roland,
There is no silver bullet.
However, there are designs that [I think] provide both GDB and the
kernel the best of possible worlds. If the kernel simply dumps out its
raw information (instead of cooking it in a way it thinks will be useful
to debuggers) then GDB can pick and choose what it really needs. This
also means that the core file and live process are both furnishing GDB
with identical data. Might even make the kernel cleaner.
