Pi first gen (B+). Hung nowhere.

=> My output at ~amd64 and Raspberry Pi (~arm) was:
=======================
fancy_user @ fancy_gentoo_host$ ./xout
Running test
Fail

Maybe a strace (with dev-util/strace) tells you more (just a guess).
If I can help with more specific informations and/or tests feel free to ask :)
