Alexander,
   Do you mean to say that you can't reproduce this failure locally on x86_64 darwin?
I am testing with current llvm 3.2 branches for llvm/compiler-rt/clang/polly/testsuite
against Xcode 4.5.2 on x86_64-apple-darwin12 using a cmake build with...

-DLLVM_ENABLE_ASSERTIONS=OFF -DCMAKE_BUILD_TYPE=Release ..

and have CC set to clang and CXX to clang++.
