The actual stderr differed from the expected stderr.
Actual stderr saved to /checkout/obj/build/x86_64-unknown-linux-gnu/test/ui/panic-handler/panic-handler-with-track-caller/panic-handler-with-track-caller.stderr
To update references, rerun the tests and pass the `--bless` flag
To only update this specific test, also pass `--test-args panic-handler/panic-handler-with-track-caller.rs`

oops good catch.

@rustbot author
as you say, needs bless

[Dylan-DPC]

@riking any updates on this? this just requires blessing of the tests so ideally we wouldn't want it being opened for a long time. thanks
