FWIW: icc rejects the code on the same grounds if run in strict more (-Xc -ansi). One 
of the reasons I can think of is that if an exception is raised somewhere in the 
constructor of B, then the member ptr<A> may have to be destroyed again, for which 
we need the destructor of ptr<A>. So it does somehow make sense to require that 
it can be compiled. This view is supported by the observation that the code compiles 
fine if you give -fno-exceptions. 
 
I don't know any normative statement in the standard to support my point of view, though. 
Nathan, do you?
