There seems to be some indeterminacy going on here; all four powerpc* platforms broke for 15.x, but the stable/13 and stable/14 builds (which I think have the same llvm code) worked fine. The weekly snapshot builds happen on amd64 hardware, so using a powerpc host is not required. > That said, I will be happy to import the fix, but it would be nice if I > can verify that it is really solving the problem. :) I have the files from the failed builds, so I can give you the logs and the preprocessed source and build script that clang reported. That might be enough to reproduce it? Let me know if you'd like those. -- Colin Percival FreeBSD Release Engineering Lead & EC2 platform maintainer Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
