Thanks for the test case! I sent a reduced version of it to HP.

It seems to me that

my_ptr<volatile Derived<int> > ptr_0 (pDer);
my_ptr<volatile Base_0<int> > ptr_1 (ptr_0);
Is essentially performing the following which doesn't cause the compiler
error to occur:
Derived<int>* const pDer = new Derived<int>;
volatile Derived<int> *ptr_0 = pDer;
volatile Base_0<int> *ptr_1 = ptr_0;
Changing the test this way would defeat its purpose: to exercise
shared_ptr's ability to perform conversions between related types
with different (but compatible) cv-qualifications.
Unless you can think of a workaround that doesn't compromise the
test's efficacy, now that we have a test case that clearly shows
it's a compiler bug we can either mark the compilation failure
of test as EXPECTED in xfail.txt or disable that part of the test.
