Bash Version: 5.0
Patch Level: 7
Release Status: release

Description:

  When logged on a machine with ssh, executing a simple command CMD1
  that spawn a "/bin/bash -c some other command" do not source
  ~/.bashrc: normal behaviour.

  When executing "CMD1 | CMD2", the ~/.bashrc is sourced: wrong  .

  I have tested that with perl and make as CMD1.

  This bug is not present in bash-4.2.48-2.fc14.1.x86_64

Repeat-By:

  Add for example in ~/.bashrc:

    echo "Sourcing .bashrc, \$- = $-"

  connect to this machine with ssh, then execute:

    $ perl -e 'exec "/bin/bash","-c","echo foo"'
    foo
    $ perl -e 'exec "/bin/bash","-c","echo foo"' | cat
    Sourcing .bashrc, $- = hBc
    foo
    $ 

Turnaround:

  For make, defines: SHELL := /bin/bash --norc

  Unsetting the SSH_CLIENT variable works also.
