#11939: Issues with boost::interprocess::shared_ptr's move constructor and move
assignment operator.
------------------------------+--------------------------
Reporter: aivazyan@⦠| Owner: igaztanaga
Type: Bugs | Status: new
Milestone: To Be Determined | Component: interprocess
Version: Boost 1.60.0 | Severity: Problem
Keywords: |
------------------------------+--------------------------
The boost::interprocess::shared_ptr's move constructor is declared as
explicit which makes it copy when user does a move. Similarly, move
assignment operator is missing to move the argument to temporary before
swapping.
{{{
boost::interprocess::shared_ptr<...> p = ...;
assert(p.unique());
auto p1 = std::move(p); // Does a copy.
assert(p1.unique()); // Fails.
decltype(p) p2;
p2 = std::move(p1); // Does a copy.
assert(p2.unique()); // Fails.
}}}
