Hello Ion,
did you look at the problem described bellow that I posted a few weeks ago.
Is it an Interprocess bug or my fault ?
Thanks for your help.

Hello Ion and others, I currently work with b::i::vectors storing b::i::managed_weak_ptr on objects created in a fixed_managed_shared_memory. I add shared_ptr whith push_back, but when I want to remove a weak_ptr using erase, the last item is erase instead of the one I want to remove. In the sample code below I add 3 objects and try to remove the middle one in both a vector of shared_ptr and a vector of weak_ptr : interprocessWeakVectorTest.cc http://pastebin.com/yDCngGw4
The result is the expected one for vector of shared_ptr, but not for a vector of weak_ptr : foo_shared_vector: 1 3 foo_weak_vector: 1 2
A tried the same with std::vectors of boost::shared_ptr and boost::weak_ptr (sample code below) : weakVectorTest.cc http://pastebin.com/fMEi0iaA
The result is the expected one for both : foo_shared_vector: 1 3 foo_weak_vector: 1 3
I don't understand the behaviour of erase on b::i::vector of b::i::weak_ptr. Is this some kind of bug or am I doing something wrong ? For information I'm doing the same kind of thing with b::i::maps of b::i::shared_ptr and b::i::weak_ptr and the behaviour is correct.
I compile this with : g++44 (GCC) 4.4.0 20090514 (Red Hat 4.4.0-6), and the 1.44 release of boost (but nothing in the 1.45 release note seems related to this), using options : -std=c++0x -lrt
I don't know why but when I remove -std=c++0x this do not compile anymore even if I don't think I use any c++0x feature (am I ?).
Can you check this or explain me my error ? Thank you. Gaëtan
