Hmm, the log has 34 occurrences of:

ld: warning: no bits should be set in UNWIND_PERSONALITY_MASK of compact unwind encoding in __LD,__compact_unwind section

followed by:

malformed __eh_frame section: FDE points to CIE outside __eh_frame section for architecture x86_64

These same errors were mentioned in #36026 by someone trying to build llvm-3.1. The issue was eventually traced to a race condition when building ld64, which was fixed by r98868.

I see in your log that you are building on /Volumes/SAN. A SAN will have different timing characteristics than a local disk. I wonder if a race condition still exists, but that it was just not observed builds done on local disks.
