The 8.2 (or 8.3) Battery Voltage Bug

We encountered behavior where the symptom is that the static initializers are not being called by a reset under certain conditions. See the recent thread Camera does not search in autonomous mode after reset for a full description of those conditions.

We don't initialize any variables in the code, but instead in each file have an explicit initialize routine such as void InitializeRealTimeClock(void) that performs the initialization. If you write code this way, you don't have to worry about what the loader will or will not do to initialize bss and data. We put all the init calls that were used for autonomous just above the inner loop as well just so we could toggle the competition port pin to test the autonomous routine over and over without hitting reset. - Didn't help with the "8.2" problem though.
