The following reduced case causes dmd to crash on Windows 7, DMD v2.059

module crash;

class A
{
    this(T...)(B root, T args)
    {
    }
}

class B : A
{
}

Normal compile using: 
dmd crash.d

Giving B a variadic constructor:
class B : A
{
   this(T...)(T args) { }
}
fixes the problem, but a non-variadic ctor does not help.

In case it is helpful, here is the Win crash report:
