Basically, if I try to use the simple mongo client data structure listed in the tutorial, I get a hard crash in Windows 7.

This is my fully-contained working example that demonstrates the issue:
```
#include <cstdint>
#include <iostream>
#include <vector>

#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/stdx.hpp>
#include <mongocxx/uri.hpp>

using bsoncxx::builder::stream::close_array;
using bsoncxx::builder::stream::close_document;
using bsoncxx::builder::stream::document;
using bsoncxx::builder::stream::finalize;
using bsoncxx::builder::stream::open_array;
using bsoncxx::builder::stream::open_document;

int main(void)
{
try {

mongocxx::uri uri("mongodb://localhost:27017");
// this is what's failing
mongocxx::client client

{ uri }

;
}
catch (std::exception err)

{ std::cout << err.what() << "\n"; }

return 0;
}
```

It seems like it's an issue deep in the Mongo callstack:
> libmongoc-1.0.dll!_InterlockedExchangeAdd64(volatile __int64 * Addend, __int64 Value) Line 5603 C

Namely, this line here:
```
do

{ // this one is what VS picks up on Old = *Addend; }

while (InterlockedCompareExchange64(Addend,
Old + Value,
Old) != Old);
```

I installed the mongo-cxx-driver using vcpkg as well.
