Ah. I've always done core sanity checks with:
1. generate core1 on old kernel
2. generate core2 on new kernel (identical userland scenario)
3. eu-readelf -nl core1 > a
4. eu-readelf -nl core2 > b
5. diff -u a b
Then you can eyeball any expected drift like SP address randomization,
and be suspicious of all other differences. (Of course, I also test
that gdb still likes it.)
Thanks,
Roland
