Using dmd 2.067.0.
This is not a bug. You need to allocate memory before you can
write to
it. Automatic allocation doesn't happen in D.
This particular part works as intended, but the other things
_are_ buggy.
Right, my point was to address an obvious misconception on how
these statements work. Other languages happily will allocate a
new array in such cases, D does not.

I knew that automatic allocation doesn't happen, but I'm confused
by the fact if you explicitly declare "c" with "int[] c;" and
then assign "c[] = a[] * b[]", versus using "auto c = a[] * b[]",
you get two different errors (array length mismatch vs no
destination memory).
