Point it out immediately. And work to create a culture that understands we all share the same goal of building more robust software. If you sense feelings are hurt, explain the common goal and point out wins the other person has had in the past.

It may also create an atmosphere of over abundant caution - which is kind of awful if you’ve ever experienced it.
