I all process libraries except one in OpenLoops, that's enough to trigger the
issue.

You can get it here (4.7M):
http://davidlt.web.cern.ch/davidlt/vault/openloops-1.1.1-stripped.tar.bz2

$ sha256sum openloops-1.1.1-stripped.tar.bz2
e8f55e404b1076f8fd8d2f42390e74dad5024d7a3b0a30dd905e4cc981628911 
openloops-1.1.1-stripped.tar.bz2

You can trigger compilation via

    cd openloops-1.1.1-stripped
    ./openloops update --processes generator=0

It takes <6 min before linking issue is hit on 8-core APM X-Gene 1. You also
need at least 4.9 GCC. With 4.8 you would hit an ICE.
