Bug reproduction:

cd clang-format-lambda-bug
clang-format -style=file main.cpp

Output:

template <typename Callback> void some_function(int, int, int, Callback) {}

int main(int, char **) {
  int a_really_long_name;
  int another_long_name;
  int a_third_long_name;
  some_function(
      a_really_long_name, another_long_name, a_third_long_name,
      [&](LineCallback line_callback) {
    int a;
    int b;
      }); // <- This is hanging in the middle of nowhere :)
  return 0;
}
