Thanks. I am out of town right now, and will be out of town for a while. When I get back I will put this on the queue of things to look at. I suspect though this can be simplified a great deal. For example, we we really need to have 3 Once the code is stripped to the bare minimum I suspect what is wrong will by crystal clear. |
My attempts to further simplify along these lines did not really get anywhere beyond this.
I was assuming the same, but the triggering conditions for this bug are non-obvious to me as removing random code that does apparently nothing can prevent the bug from being hit. |

In the future I will write a guide to make it easier for you help me to help you ;-) |
