Hash FMX demo crashes on Android 32 bit in release mode

[MHumm]

The Hash FMX demo app crashes when compiled as release mode Android 32 app. When compiled as Android 32 bit debug mode app it works. The reason is not known yet but it will be investigated.

Some user reported that this code is sufficient to crash it already:
`uses
DECHash

var
Hash: THash_MD5;
begin

Hash := THash_MD5.Create;
Try
sleep(1000);
Finally
Hash.Free;
End;`

Yes just gave Cipher_FMX test under 10.4.2 and 32-bit debug mode works while release hangs on start-up
