<p class="MsoNormal"><span style="font-size:10.5pt;color:black">It appears that the MSVC debugger is checking to make sure variables are set before used as an argument to a function. (Cool feature. I didn't know it did that.) It looks like I violated that.
I am pretty sure this is benign; the state that leads to uninitialized variables should mean they won't be used in the function. It's still bad and dangerous practice though, so thanks for pointing it out.<o:p></o:p></span></p>
