Hi,
I just tried to do this on my laptop and it worked fine, with fslmaths not using more than 4.3GB - at least not that I saw. It is possible that there is a brief moment when a temporary copy is created (given that the combined image itself is 4.2GB in size) and in that case it will need a little over 8GB. However, swap space should cope with this.
So what version of FSL are you using and what exact OS?
All the best,
Mark
