Yeah. How would this scenario come into being though? Suppose you have 
1.64.0 already installed; you replace boost_assert from develop and now, as 
also mentioned a number of times, you have all manners of ODR violations 
because your libraries are built against boost_assert 1.64.0 and you're 
including the develop one.
