I noticed this difference in our reports:

using Apple clang version 2.0 (trunk 125236) (based on LLVM 2.9svn)

I think I was getting the clang++ in /usr/lib/ instead of in
/Users/jonkalb/Documents/development/developement/build/Debug+Asserts/bin/

Could that be the issue? I've changed my PATH so I now get:

Jon-Kalbs-MacBook-Pro:test jonkalb$ which clang++
/Users/jonkalb/Documents/development/developement/build/Debug+Asserts/bin/cl
ang++

and I'm running testit again. I will send the entire result to you off-list
if it isn't closer to your result.

Thanks.
