Why is SysTime.init invalid?

[ed]

Hi All,


I'm trying to use SysTime in a struct but I've noticed the 
following:

(A) SysTime.init leads to a crash.
---
void main()
{
     SysTime t;
     writefln("t:%s", t);
}

% ./dtest
zsh: segmentation fault (core dumped) ./dtest
---

(B) Initialising a SysTime member directly fails
---
struct T
{
     SysTime t=SysTime(0);
}
datetime.d (28538) Error: static variable _lowLock cannot be read 
at compile time
---

Which means I have to provide a default ctor for my struct but do 
not know how.


1. Is this by design or is it a bug?
2. Is there a way to provide a default struct ctor so I can init 
the SysTime member?

If this is by design I don't think it should crash. A Date/Time 
error is often something user code can safely recover from.

Thanks,
ed
