[Harry Potter] What would happen if Voldemort broke an unbreakable vow whilst still having horcruxes?

Would one of the horcruxes get destroyed perhaps?  Or would Voldemort (or any other wizard with a horcrux) be unable to make the unbreakable vow in the first place?

His spirit would be ripped from his body in a similar fashion to when the killing curse reflected back at him when he tried to kill Harry Potter. He would have to wander as a disembodied spirit until he was able to get a new body.
