I confirm the problem when following this procedure step by step.

Thank you, Eric, for the confirmation.

Just to clarify for anyone following along: the problem isn't with
bash or trace-cmd themselves. If I perform the same steps but use
'bash' first, then 'trace-cmd', adding 'bash' succeeds but later
adding 'trace-cmd' causes 'trace-cmd' to fail in the same way 'bash'
did when it was added second.
