Try something like this (untested):
alias float TF;
TF[] f = (cast(TF*)std.gc.malloc(x * TF.sizeof))[0 .. x];

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.
