The failure appears on the compilation on the gcc-4.7 and gcc-4.8 packages. If you make a `manifest.scm` that looks like this: (use-modules (gnu packages gcc)) (packages->manifest (list gcc-4.7)) And you try to compile that using `guix build -m manifest.scm` the compilation fails. The same happens when choosing 4.8. I'm on x64. Hope that clarifies a little bit.
