Beta 2.072.0-b2

[Sönke Ludwig via Digitalmars-d-announce]

There is an error [1] (caused by [2]) in taggedalgebraic, because void 
initializers for pointer types are now invalid in safe code. The 
question now is, is there any workaround that can be done in the 
library, or will every library user have to fix this?

Of course, the new error is more restrictive than it should be, namely 
if the uninitialized pointer field gets written before the first read, 
it would still be safe.
