Apparently it's the same thing as the old AA problem.
Essentially the
buffer would have to be initialized first by appending:
Yeah... same old, same old.
I think you can work around the problem using "appender":
auto buffer = appender!(int[])();
This is off memory, so not 100% guaranteed, but I remember this
worked for me last time *I* ran into this problem.
Indeed, this is a recurring problem in D with non-initialized
reference types, AA's, Appender, Containers...
The fact there is no standardized way to make a call for run-time
intialization with no arguments doesn't help either. I had made a
request for having an explicit runtime constructor that takes no
arguments:

Didn't really get anywhere though...
In any case, I think this is a ***HUGE*** problem for D (my N°1
problem anyways). static opCall() kind of helps, but it's not
quite a constructor...
I think we're kind of doomed to keep this issue around
unresolved, biting users in the ass *everyday*, for still quite
some time :(
