438,shared_ptr/weak_ptr tests are not C++ spec compliant,nobody,Peter Dimov,"{{{
Please refer to the latest C++ spec (Second edition,
2003-04-01), section 12.8.15, ""Copying class objects"".
Look at your source code in test/weak_ptr_test.cpp.

1. You cannot assume the reference count of the
shared_ptr going into the copy_assignment function is
one. The spec says that compilers are allowed to make
an optimization to eliminate a copy, but not mandated
to do so. This means that the effective reference count
upon entry to the function may be two, not one.

To correct your unit tests, forcibly create a local
object that you pass by value to guarantee the
reference count is two upon entry for all compilers.
