I just tried this out with current mainline, and I couldn't figure out any wrong
behaviour.  Could you please try this out with current mainline gdb?

If things still look wrong to you, then please could you paste a full log of the
session, showing more clearly what is wrong?  The way it's reported, it makes us
have to reproduce the issue every time we want to remember gdb's output.

This is not so much a bug as it is a feature request. I think it should be
possible to implement this feature using the new Python interface but I haven't
tried yet. I can almost use a hook for this purpose:

.gdbinit:
define hookpost-restart
checkpoint
end

This hook isn't ideal though. First, it creates the checkpoint even if the
original checkpoint hasn't moved. Second, while that location in program
execution is saved through the new checkpoint, the original number moves.

.gdbinit:
define hookpost-restart-and-move
checkpoint
restart $last
end

With this behavior, the checkpoint behaves more like a CVS tag (once created it
can never be moved) than a branch.

This behavior makes more sense because in my mental model a checkpoint is a
point of execution, not a process. Using the example from the documentation,
when you bookmark a page, you are thinking of the last page you read, not page
697 because the number isn't useful to you except to find the last page you
read. This behavior would make even more sense if GDB added a new feature to
label checkpoints like variables (ie "set $packetSent = checkpoint").
