Comment(by wad):

 You don't have to power-off for this to happen.

 Clear the bit, and then wait for a while.  It will be reset.

 A first check of Vbat shows that it doesn't glitch or droop during a power
 cycle, or when this bit sets itself.   The supposition is that this is
 actually due to noise impacting the RTC oscillator itself.
