Why yum command fails with "Aborted (core dumped)" error as root user only?

Issue

• yum/dnf commands are failing with Aborted (core dumped) error as root user only:

    # yum repolist
    Aborted (core dumped)
    # yum clean all
    Aborted (core dumped)
    # yum list all
    Aborted (core dumped)
  

• yum/dnf commands are running as non-root user without any issues.
