    Description

      Just typing the following code (without even saving the file) causes 1 of 4 CPU cores go to 100% load. After a minute or so, all 4 cores are 100%.

      p->any_member_function();

      p is declared as unique_ptr<Base>.

      Derived class is defined as follows:
      template<class T>
      struct Derived : Base

      { T var; member_function_1(); ... }

      unique_ptr<plain old data struct> does not cause any issues.
