Really thanks for your help! This patch is for crunchide to handle ELF object file in a more general way, but not be limited to the custom section layout (i.e., section headers, .symtab, and then .strtab are @EOF). And if we are still using ld(1), I think the patched crunchide should produce exactly the same output as before. Then the rescue binary would also be the same. I checked and verified the intermediate object files and rescue binary (via binary diff) on X86 FreeBSD 9.0. If you can also kindly help check this on different archs and feedback, I think the result will be very helpful.
