Maybe I misunderstood, but which build is this?

Sorry, I misunderstood and thought you meant that the newer patch was working.

I wonder if certain things happening, like interrupt processing, during a voltage change can cause glitches in operation. I really should patch my Fuze V2 with this scaling patch and dive deeper.

Are you sure theres no possible race condition in there? I don't see how interrupt processing would be more of a problem then audio decoding, and given that it seems to crash on probably the first or second voltage change, its apparently extremely likely to occur in an ISR but rarely or never happening otherwise.
Plus the fact that it happens on the Fuze v2 but not Zip/Clip+ which have the same SOC makes me wonder if some other thread or peripheral specific to the fuze (scrollwheel, buttons, DBOP, etc) that causes this.
