docker build fails with image but not source code

[DarkninjaD]

I'm not someone who knows a lot about docker and it's build process, but for some reason. if I build using the image "urre/wordpress-nginx-docker-compose-image:1.4.0" it fails with a segmentation fault when a process calls "libc-bin" on the apt-get command step. but if I copy and paste the source code of your Dockerfile it works. I don't get it but I want to let you know is some how.
