For example if i create a vector; 

```
std::vector<std::string> aVector { "this", "is", "a", "standard", "list"}

```

in the normal gdb command line i would get 


```
p aVector 
$1 = std::vector of length 5, capacity 5 = {"this", "is ", "a", "standard", "list"}

```
however in GDB/MI


``` 
-var-create - * "aVector"

--
result-class: done
name: var21
numchild: 0
value: {...}
type: std::vector<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >
thread-id: 1
displayhint: array
dynamic: 1
has_more: 1

```

the to_string value of the std::vector pretty printer is gone and replaced by "{...}"

the values is meant to show the size of the vector and very valuable when debugging.

with the help of my mentor i was able to get the relevant part that it is hardcoded to return `{...}` (there may be other parts) that may be relevant.
