cdbstack - last sample is dropped

[wmascia]

The last sample in the file doesn't get added. So I added the following on line 119 of DebuggerStackSource.cs just after the end of the for(;;) loop. Just a copy/paste from the code above (including the sample.Metric = 1 per Issue 1009 - No metrics in cdbstacks).

            if (stack.Count != 0)
            {

                StackSourceCallStackIndex parent = StackSourceCallStackIndex.Invalid;
                for (int i = stack.Count - 1; i >= 0; --i)
                {
                    parent = Interner.CallStackIntern(stack[i].frame, parent);
                }

                stack.Clear();

                sample.Metric = 1;
                sample.StackIndex = parent;
                sample.TimeRelativeMSec = time;
                time++;
                AddSample(sample);
            }

UPDATE: added the src file name

@wmascia can you share the data file where you saw this issue?

[wmascia]

It would happen on any cdbstack file but you can use the one below. Granted you'd never actually care about this in a typical trace with bagillions of samples. I just happened to notice it when I had a small cdbstack file with an interesting frame in the last stack ...which I couldn't find in the stack viewer.

In this case A!foo and A!baz will be included but B!foo and B!baz will not.

test.cdbstack:

Call Site A!foo A!baz

Call Site B!foo B!baz

(Doh I mentioned the line number but not the src file in the OP. Just updated it)
