Auto-complete adds parentheses at the wrong place.

Reported by Zachary Turner Mar 10, 2017 at 07:53 PM C++visual studio 2017 intellisense Fixed-in: Visual Studio 2017 Version 15.4

Given the following code:

#include <string>
int foo(const std::string &Str, int X1, int X2) { return 0; }
struct Bar { int baz() { return 42; } };
int main() {
  Bar B;
  // foo("Test", B.baz(), B.baz());
}

Place the cursor under the commented line and retype the commented above line exactly as it appears (without the comment). Actually type the entire the line that calls the foo function.

As soon as you type the semicolon, auto-complete injects an extra parentheses after the first call to B.baz(), producing syntactically incorrect code. i.e. it transforms that line into this:

foo("Test", B.baz()), B.baz());

I have the exact same problem. It also happens in a for loop and similar scenarios. For example:

vector<int> v;
// for(int i = 0; i < v.size(); i++)

As soon as I put a semicolon after v.size(), visual studio inserts a random closing parenthesis after this token and then the code line looks like this:

for(int i = 0; i < v.size()); //i++)

Was present in 15.3.1, still present in 15.3.2; pretty sure it was present since VS2017 release. This is easily the most annoying VS bug I've seen and it is also a productivity killer. I had to switch off parentheses completion (turned out I like it better that way), otherwise I'd see this bug literally every few minutes if not every minute!
