</span>Joe, thank you confirming my hunch. I've gone ahead and done that.<br>

<br>
As you might imagine this is now a blocking bug for my project. I'd<br>
really like to fix this as soon as humanly possible.<br>
<br>
I also realize that, while a priority for me, it is may not be for<br>
anyone else. With that in mind, my assumption is that if its going to be<br>
fixed "soon" I probably need to fix it myself. Unfortunately, I have<br>
little experience with this and would not know where to begin. Is there<br>
anything I can read that might explain how to begin debugging the<br>
compiler?<br>
