These do seem to be spurious and caused by dwarfdump not dealing with the relocations for the start symbols in the eh_frame. For these cases, ld64, BINUTILS objdump and LLVM objdump are all happy that the FDEs are correctly formed - so (a) they don't seem to be a problem and (b) the m64 unwinder should never be used on any Darwin >= 10 anyway.
