Looks like you're using linux, on x86_64... which is what I'm using so I can't understand what's happening here, unless perhaps there is a problem with your gcc 4.7.2 installation?

I searched for the ###\n### garbage on google, and got this: 

https://svn.boost.org/trac/boost/ticket/5880

Also found this stackoverflow question which may help:

Sorry I can't be of more help!
