The interprocess document gives the prototype for `construct()` as
MyType *ptr = managed_memory_segment.construct<MyType>("Name")
(par1, par2...);
but when I try
MyVector *myvector = segment.construct<MyVector>("MyVector")(100,
alloc_inst);
I get compilation errors.
This is because vector doesn't have such a constructor.
Try (100, 0, alloc_inst)

Works like a charm, thanks a lot! I checked std::vector doc and saw that it's
constructor is
explicit vector ( size_type n, const T& value= T(), const Allocator& =
Allocator() );
so you're right. 
Stupid question: if this is the constructor, how does 
std::vector<int> v = std::vector<int>(100)
work?

Thanks a lot,
