--- Comment #2 from Tom Tromey <tromey at sourceware dot org> ---
'numchild' isn't reliable for a dynamic varobj.
This is documented in the MI docs:

'numchild'
     The number of children of the varobj.  This number is not
     necessarily reliable for a dynamic varobj.  Instead, you must
     examine the 'has_more' attribute.

This is a little confusing because in this command:

-var-list-children --all-values struct1.public
^done,numchild="1",children=[child={name="struct1.public.a",exp="a",numchild="0",value="{...}",type="std::vector<int,
std::allocator<int> >",displayhint="array",dynamic="1"}],has_more="0"

... the has_more here refers to 'struct1.public' (which really only
does have one child), and 'a' doesn't have a has_more here.
Instead one must list the children of 'a' to find out.

So, I'm somewhat inclined to mark this as not a bug.
