Sadly, that doesn?t help either. Over the past day, I?ve built and installed a
different branch of the OS (stable/11, instead of release/11.1), to see if a new
compiler/libc might change things. Sadly, it does not.
In the same situation now, auth fails immediately with signal 11. Running gdb
on auth (from build dir, compiled -g -O2) shows something similar.

Hi! Unfortunately we do not have a Sparc64 with any OS at hand. Maybe you could break main r s until it breaks?

Next step I?ll stop before that and be more careful about n?ing things, but.
Just passing on context while I have it.
Thanks. More later.
