I think you'd have to change the implementation of the std containers
to make it work because many would use pointers and these would have
to be derived from the 'struct _ptr' defined in cppgc.hpp in order
for them to be registered in the pointer data base as described in
my other post:

Do you have any other idea about how it can be done?
