This problem appears analogous to the at_exit problem in newlib fixed by
Thomas Pfaff here:

I assume a similar fix is in order, but I don't currently have to time to
cook one up and test it.  Is anyone else game?

I'll give it a try when I free up if no one else gets there first.  BTW, a
pass through newlib looking for other similar occurences appears to be in
order.
