As this is not checked within scoped_array::reset or further down the callstack in scoped_array::swap, a checked_delete was called on a nullptr and threw a Segfault. For me, I'd consider this a bug as scoped_array assumes ownership and hence is responsible for delete it's allocated memory. the problem occurred during an ill-posed usage of the boost utf as documented in the file attached.
