I fail to see any real difference from the OP's code:

- Why the alias?
- std.gc.malloc returns the array with correct length according to my quick test, so the 
use of [0..x] is redundant
- using TF.sizeof instead of 4 might fix things if on the user's platform float isn't 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.

But knowing what platform the OP is using and having a complete testcase for the AVs/ABEs 
might help to understand what is going on.
