Also, with a very small test shared lib and a small test binary that uses that lib, I get a segfault at runtime if I've run the library through etharden, even with the --nop
flag. I'm getting the same segfault in my own tool without modifying the ELF file- just parse and then generate.
Should I make an issue for this?

I made an issue for the segfault (#37)
from egalito.
Check if your seeing "Warning: not populating PLT entries" error message with -v. I'm about to get into the same problem this evening. You can also verify if its the same thing by running: etelf ../src/ex/hello hello.test. Check gdb on both, disass main, and see whats going on with the "puts" function, and whether it leaves just an address (not plt resolving) on the modified version. If this is the same issue I'll post more information later.
Update:
I suggest you grab the artefact / virtual machine image for qemu/kvm (https://github.com/columbia/egalito-artefact/blob/master/README.txt) to do any tests you wish. I believe several parts of the code may need to be changed to work properly on the newest ubuntu. I haven't decided if I will continue with egalito as an approach considering it may take more time than alternatives to bring it up to speed for what I need. Good luck
