Now we retested with trunk:r139788 on Mac OS X 10.7.1 - it still fails, but now we have a bug report with a minimized test case:

http://llvm.org/bugs/show_bug.cgi?id=10931

Also, the following case is problematic to get clang working on Solaris, but that is a separate issue:
http://llvm.org/bugs/show_bug.cgi?id=5172

(clang/llvm builds out of the box now with gcc, but the resulting compiler can’t build itself due to 5172)

Cheers,
