alignment error in FCReadFloat64 on 32 bit devices about fastcoding HOT 4 OPEN

I don't understand how this could possibly work. Can you provide a sample project so I can verify before I merge the fix? Thanks.

I checked and it looks like double_t isn't what I thought it was (it's defined as being a minimum of 8 bytes, rather than exactly 8 bytes). I've changed the definitions, so hopefully it should work now (version 3.2.1). Let me know if not.

I found the issue occurs on the iPhone 4s when _input is misaligned. When cast as a double, the device tries to load 8 bytes into a floating point register. When cast as an int64, 8 bytes are loaded into a general purpose register. Unlike the float registers, the general purpose registers can work with misaligned data.

The data shouldn't be misaligned in the first place though: that's the point of the align statement.
