Ctor Initializer: self initialization causes crash?

Question

I had a hard time debugging a crash on production. Just wanted to confirm with folks here about the semantics. We have a class like ...

class Test {
public:
  Te         


        

Answer 1

This is the same difference as between

std::string str;
str = str;

and

std::string str(str);

The former works (although it's nonsense), the latter doesn't, since it tries to copy-construct an object from a not-yet-constructed object.

Of course, the way to go would be

Test() : m_str() {}
