Try something like this (untested):

I fail to see any real difference from the OP's code:
- Why the alias?
Because in that code I have used three times a type (TF), auto allows to remove
only one of them. The alias is not the best solution (a better solution is to
put that code into a templated function), but repeating the same generic type
more than one time is usually a source of bugs.
- std.gc.malloc returns the array with correct length according to my quick
test, so the
use of [0..x] is redundant
Really? Well, as I have said I have not tested that code.
Generally GC functions return a void*, so to create an array I think you need
to slice it... What is the code of your quick test?
- using TF.sizeof instead of 4 might fix things if on the user's platform float
isn't 4
bytes long.
In D I think float is always 4 bytes long.
Otherwise, while using .sizeof instead of a hard-coded number is better
practice, it isn't going to get rid of an AV.
I don't know what an AV is.
