bug#22114: 24.5; [PATCH] Allow profiler.el to display reports after stopping

[Vasilij Schneidermann]

Meanwhile, I've come up with a simpler approach to solving this at the C
level.  Basically the problem is that if log is exposed, it cannot be
used again from profiler.el.  What if one would just create a deep copy
of the log that can be safely used externally?
