For any global static objects A and B ending up in libA and libB resp,, 
if libB (directly or indirectly) depends on LibA that enforces that the 
A ctor is called before the B ctor and the A dtor is called after the B 
dtor.  But order becomes unspecified as soon as you place A and B into 
the same library, so I assume something of that nature causes the 
problem for you there.  As always, global static objects are evil.
