> They had discovered that you could clear a string under MSVC by `memset()`ing over it. Why was that? Was it too problematic to just call std::string::clear ?

  I'm guessing the string was part of a larger struct, and they wanted to clear the entire struct with a single memset. It's a somewhat common pattern in C, but requires care.
