There was a problem hiding this comment.
sed -i does not work on macOS. So I changed it to -i.bak at #10201

The tac-continue test used to rely on having an accessible TMP_DIR, the test was changed and now it was updated to be more flexible. Ultimately the functionality of tac in our implementation compared to the GNU implementation was just different from the context that the stdin is buffered to a TMP_DIR in the GNU implementation and not in the uutils implementation. This can cause issues with large STDIN because it will always max out the memory and timeout instead of erroring and it takes up significantly more memory.
