Same issue as reported by Smokin Jake to the email list on 6 April still happens with version 3.0.3pre2.
sudo rsync -avXH --fileflags --crtimes /Src/ /Dst/
does not copy extended attributes according to backup bouncer. Adding -A to the argument list does result in the extended attributes being copied.
This is on a 64-bit Intel Mac, if that matters:
rsync version 3.0.3pre2 protocol version 30

64-bit files, 32-bit inums, 32-bit timestamps, 64-bit long ints,
socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
append, ACLs, xattrs, iconv, symtimes, file-flags
A stock rsync works fine, but after applying the fileflags patch, the xattrs test in the test suite starts to fail. The reason for this is that the get_xattrs() function has started to reject device and special files (due to a buggy errno return from xattr functions), but the st_mode value in the stat struct was not being set prior to the call in flist.c.
The fix is to add this line:
sx.st.st_mode = file->mode;
prior to the call of get_xattrs() in flist.c. I'll make that fix in the git repository.
