Thank you, Greg, for the good explanation and your time
and sorry for the wrong bug-report.
Best,

--rcfile takes an argument. It has to be followed by the name of the
rc file that you want bash to read.
When you write --rcfile --login you're telling bash that its rc file
is named "--login", and that it should read this file, instead of ~/.bashrc,
if it needs to read an rc file.
However, since you also gave the name of a script to execute, bash doesn't
need to read an rc file. So, it simply ignores the --rcfile --login
that you gave it, and just executes test.sh.
On the other hand, when you write --login --rcfile test.sh
you are telling bash that its rc file is named "test.sh", and that it
should read this instead of ~/.bashrc if it needs to read an rc file.
But since you're using the --login argument, bash doesn't need to
read an rc file. So, it doesn't make use of the --rcfile test.sh
arguments. You're basically just running bash --login .
