 I am not familiar with the trunk tests.  However XL 10.1.0.3 AIX is the
latest C++ compiler. This
use vacpp as the bjam toolset argument. But internally I gather it uses xlC.

When I ran the sample in the Totalview(debugger) it shows the following.

Can't read type info for "basic_pointer_oserializer": Expecting mangled
name, and didn't find one.
Can't read type info for "basic_pointer_iserializer": Expecting mangled
name, and didn't find one.
Can't read type info for

>From your reply your saying that this is a compiler bug
Do you know if any defect report has been raised ?
Is there any workaround that stops the compiler doing these optimisation.

If not is there possibility of changing the serialization code ?
