Crash saving strat analyzer results

[Pete S]

Unfortunately I can't give an exact series of steps to reproduce this, but in general it's:

1. Create an instrument list with 10 stocks
2. Run a backtest on the list itself, using around 3 months worth of 5 minute data
3. Save the results

Every couple of times, you will get a crash with this stack trace in the trace file:

I had reported a crash on this flow earlier; it seems to occur less frequently now and the stack trace is different.

We added more code to cover this issue. Please let us know in case this happens again after next NT6.5 update. Thanks for reporting.

Issues around saving of strategy results appear to be completely resolved with the latest beta -- I've been doing a lot of this and have not seen any problems.
