Dan, are you trying to run an executable with a custom LC_LOAD_DYLINKER command?

I understand that, I think. TBC, I'm definitely not trying to overwrite /usr/lib/dyld, which I would expect to be blocked by SIP. Instead, I'm trying to build a new mach-o file that points at a dyld that I'm building myself. Would you expect SIP to block that? I'm seeing some weird behavior that I believe is due to SIP, but I might be misattributing the failure.

Thanks,
Dan

Any experimentation with system-level components requires disabling SIP, as well as potentially rebuilding other open source components of OS X.
