I'm just as guilty of not following up on my own report.

I run the root-only tests as:

make NON_ROOT_USERNAME=nobody check-root

I get no failures during that run.

I run the other tests as:

su nobody -s /bin/bash -c "make RUN_EXPENSIVE_TESTS=yes check"

It's here that the getlogin test fails.  I don't care so much about the
odd(ish) tty issues for now.  However, the assert in getlogin.c:60-61 that
assumes getlogin() and getenv("LOGNAME") always returns the same name fails
when run under 'su' as shown above, and as recommended in README.

Hopefully, that failure is easy enough for anyone to reproduce.  At some
point I hope to get more time to look into the tty issue.

Regards,

Matt.
