That's because in function mi_cmd_data_evaluate_expression the option to
dereference references is disabled:
  opts.deref_ref =3D 0;

I made a quick test and enabled this option in the debugger, then the result
looks like this:

(gdb) interpreter-exec mi2 '-data-evaluate-expression v[1]'
^done,value=3D"@0x3c20d4: 2"

Not sure why it is like this, but this might be intentional.
