This problem has nothing to do with bind (which doesn't allocate memory).

Throwing from a deleter is a no-no (and generally a bad design), since the
only time it gets called is by shared_ptr's destructor.  Don't do that.
 This is very likely to be a terminating condition using std::shared_ptr in
C++0x.
