=============================================================

I'm not sure where this should go, but I came across this example of what seems to be crash signature name unmangling failing.

The line of code is just:
  histogram.Add(value);

So I don't think there's any weird closure or anonymous function stuff involved.

This function name is so large it messes up the crash-stats table that includes it.
