std::shared_ptr<std::vector<std::shared_ptr<...>>>

Hi,
I'm having a To-Many Relationship :
OvenData ----*>ProgramData
using C++11 containers and smart pointers
This worked fine until I changed the relationship using a std::shared_ptr to the std::vetor:
std::vector<std::shared_ptr<dal::ProgramData>> programs_;
to
std::shared_ptr<std::vector<std::shared_ptr<dal::ProgramData>>> programs_;
Persistent data file excerpt:
...
namespace dal {
#pragma db object pointer(std::shared_ptr) session
#pragma db object table("programs")
class ProgramData {
...
std::string program_name_;
...
}
...
#pragma db object pointer(std::shared_ptr) session
#pragma db object table("ovens")
class OvenData {
...
#pragma db value_not_null unordered
std::shared_ptr<std::vector<std::shared_ptr<dal::ProgramData>>> programs_;
};
...
and ODB compiler crashes:
...

I'm on Deian Stretch using quite old ODB 2.4.0.
Is it possible to use
std::shared_ptr<std::vector<std::shared_ptr<...>>>
as 'To-Many Relationship'?
Anyway ODB compiler should not crash.
Best regards
Carsten
