#3210: dynamic_cast fails between modules
-------------------------------+--------------------------------------------

Version: Boost 1.39.0 | Severity: Problem

in file: python/detail/wrapper_base.hpp:64
function:
namespace wrapper_base_ // ADL disabler
{
template <class T>
inline PyObject*
owner_impl(T const volatile* x, mpl::true_)
{
if (wrapper_base const volatile* w = dynamic_cast<wrapper_base
const volatile*>(x)) /*this dynamic cast fails */
{
printf("dynamic_cast: OK\n");
return wrapper_base_::get_owner(*w);
}
printf("dynamic_cast: FAIL %s:%p\n",
boost::python::type_id<wrapper_base>().name(), x);
return 0;
}
this dynamic cast fail:
" dynamic_cast<wrapper_base const volatile*>(x) " when type of x not is
not in the current module, this cause boost create a new PyObject for the
c++ pointer.
