To clarify more, here's what I get with MI:

   -data-evaluate-expression *p3
   ^done,value="{int (int)} 0xb7ee6e9c <__DTOR_END__+4>"
   (gdb)
   -var-create VP3 0 *p3
   ^done,name="VP3",numchild="0",type="int (int)"
   (gdb)
   -var-evaluate-expression VP3
   ^done,value="{int (int)} 0xb7ee6e9c <__DTOR_END__+4>"

The type enclosed in {} is still there.
