Bash keeps it's history internally until it exits. This is why your .bash_history can be empty while you see old commands. This is also the reason why, when closing multiple instances of bash (eg. terminal sessions), only the commands from the last closed session can be found again.
To completely clear, you'll have to remove .bash_history without running bash.

SYNOPSIS
bashbug [--help] [--version] [bug-report-email-addresses]
DESCRIPTION
bashbug is a utility for reporting bugs in Bash to the maintainers.
bashbug will start up your preferred editor with a preformatted bug report template for you to fill in. Save the file and quit the editor

sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed
by giving a comma separated list of bug-report-email-addresses.
If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent.
