Explicit default constructed chrono::durations are uninitialized

[Joachim Faulhaber]

For boost::chrono::durations the default constructor is supposed to work like this:

typedef std::chrono::duration<int> D;
D d1;       // d1.count() uninitialized
D d2 = D(); // d2.count() zero-initialized

In the current implementation, durations d1 and d2 are uninitialized. Yet d2 should be initialized by zero.

Hi,

I don't remember when I committed a fix, but the code now is

duration() : rep_(duration_values<rep>::zero()) { }

Please reopen the ticket if you have any issues yet.

I have just found it, It was fixed by Changeset #70074
