defaultTargetOS is a trivial leaf function:

Target.OS defaultTargetOS()
 {
     static if (TARGET.Windows)
         return Target.OS.Windows;
     else static if (TARGET.Linux)
         return Target.OS.linux;
     else static if (TARGET.OSX)
         return Target.OS.OSX;
     else static if (TARGET.FreeBSD)
         return Target.OS.FreeBSD;
     else static if (TARGET.OpenBSD)
         return Target.OS.OpenBSD;
     else static if (TARGET.Solaris)
         return Target.OS.Solaris;
     else static if (TARGET.DragonFlyBSD)
         return Target.OS.DragonFlyBSD;
     else
         static assert(0, "unknown TARGET");
 }

is it hitting the static assert?

Nope, reduced:

---
Target.OS defaultTargetOS()
{
    return Target.OS.linux;
}

struct Target
{
    enum OS { linux }

    OS os = defaultTargetOS();

    void deinitialize()
    {
        this.init;
    }

    @property isPOSIX() scope @nogc
    {
    }
}

And removing the deinitialize function causes:
---
dmd/target.d(10):        called from here: defaultTargetOS()
dmd: todt.c:77: virtual void Initializer_toDt(Initializer*,
DtBuilder&)::InitToDt::visit(Initializer*): Assertion `0' failed.

And to confirm this is dmd-cxx compiling dmd master that fails?

Yes, which may mean some older versions of dmd fail too.

I say may, what I really mean is very likely.

Tracked it down, the ICE is related to, and is fixed by issue 19415.
