The files requested when it crashed

This occurs on the latest version from branches/release_36 228902, I also tried
it with 3.6 rc2 and it's still crashing, so I'm not sure what's going on, I'm
pretty sure it was working before.

Also, this is the same machine that builds the boost tests (BP x86_64 C++11):
<a href="http://www.boost.org/development/tests/master/developer/summary.html">http://www.boost.org/development/tests/master/developer/summary.html</a> and that's
building fine.
