Nice trick, it surprisingly compiled.
I found meanwhile though that the problem is more general: whenever a new
instance of AlignedType is created from python, it will be possibly mis-aligned,
because the Python allocator does not care about alignment: it simply provides a
chunk of memory based on PyTypeObject.{tp_basicsize,tp_itemsize} for the type
being instantiated.
A possible workaround (though quite laborious) is to use the overloaded
operator new ot AlignedType, which aligns properly, and write all ctors
of the wrapped class such that pointer (manage_new_object, I assume?)
is returned:
namespace py=boost::python;
static AlignedType* AlignedType_new(){ return new AlignedType; }
static AlignedType* AlignedType_copy(const AlignedType& other){
return new AlignedType(other);
}
py::class_<AlignedType>("AlignedType",boost::python::no_init)
.def("__init__",&AlignedType_new)
.def("__init__",&AlignedType_copy)
;
Isn't that insane? Is there a better way?
Cheers, v.
