I guess so.

"bash --login" works fine, but the problem with "-bash" prevents chere
from starting login shells. It may be possible to modify chere to use
"bash --login", but this is still a bash bug, right?

As I said, I noticed the problem first with chere. I confirmed the
problem by adding

    echo "`date` ~/.profile" >> /tmp/dotfile

at the top of ~/.profile. When I start a shell with "bash --login", I
see the current date/time added to /tmp/dotfile. If I execute "exec -l
/bin/bash", no entry is added to /tmp/dotfile with 3.1-1. An entry is
added with 3.0-14.

Your program is sick!  Shoot it and put it out of its memory.
