Global variables in different TUs are initialized in an undefined order. At least one global variable was accessing a global switchover variable. This caused the switchover variable to be initialized in an incorrect state.
Since the switchover is always explicitly set before transaction processing, this bug can not effect transaction processing, but could effect unit tests (and potentially the value of some global variables). Note: at the time of this patch the offending bug is not yet in production.
