Comment (by mgaunard):

 I am getting tons of related errors, some of which come from using
 exception_ptr (which uses shared_ptr and checked_delete under the hood) to
 transfer exceptions between threads.

 warning: deleting object of polymorphic class type
 `boost::error_info<boost::tag_original_exception_type, const
 std::type_info*>' which has non-virtual destructor might cause undefined
 behaviour [-Wdelete-non-virtual-dtor].

 This happens with -Wall on GCC 4.7.

 The fix is trivial, please just include it.
