code and pretty printer example

OS: Ubuntu 18.04
gdb version 8.2
gcc version 7.3.0

Pretty printing enabled for an object with a child object, -var-create shows a value of {...} even though gdb in normal mode ("p <object>") shows that it has a value.

With pretty printer enabled, "p d" gives 
1: (613612) ->~"$2 = \"Test\""
1: (613613) ->~" = {value1 = 1"
1: (613613) ->~", value2 = 2"
1: (613613) ->~", dc = \"Child\""
1: (613613) ->~" = {child_value1 = 9"
1: (613614) ->~", child_value2 = 8"
1: (613614) ->~"}}\n"

but -var-create - * "d" gives 
^done,name="var10",numchild="0",value="{...}",type="test::debug",thread-id="1",dynamic="1",has_more="1"

Sample .cpp and pretty printer python file are attached.
