I think you may be hitting the libthr issue that was introduced in
r234947 (Thu May 3 09:17:31 2012 UTC) and fixed in r235068 (Sat May 5
23:51:24 2012 UTC).  This caused some programs to randomly bomb out with
bus errors or other weirdness.

Please try building and installing lib/libthr (from your updated source
tree) before running the rest of the world/kernel build.
