[Boost-users] Boost 1.35 weak_ptr::lock

Hello, I'm trying to update my codes Boost from 1.34.1 to 1.35 and I'm getting a test case failure dealing with weak_ptr. I have an std::vector of weak_ptr's and I've verified that the weak_ptr that get put in are valid. Then later I look through the whole vector and lock the weak_ptr's to call a virtual method on them. The weak_ptr says it's (!expired) and the (shared_ptr == true). But the vtable is all messed up and the shared_ptr's px is not a pointer to something I made the weak_ptr from. Soo... is there any idea about why the weak_ptr from 1.35 would do this when the weak_ptr from 1.34.1 works fine? The headers look remarkably the same so I have no idea. Thanks, Aaron
