What steps will reproduce the bug?

Unfortunately, the files readline has trouble with are proprietary and I can't share them. I have some ideas on how to craft one, but it would take some time, so I'd like to see first if it will be needed at all.

How often does it reproduce? Is there a required condition?

Consistently. Isn't present in 19.2.0 and earlier.

What is the expected behavior?

No \r in any of the lines.

What do you see instead?

Some of the files (not all) produce 1-3 lines with an \r in it. In one file it happens 21870 lines in (109243 preceding characters), in another 75432, in another 120396. I see no pattern, but it's deterministic.

Additional information

Here are a few lines from one of the files:

 0 VERTEX 8 14 10 22.0936 20 12.9141 0 VERTEX 8 14 10 22.8017 20 12.4141 0 VERTEX 8 14 10 23.6255 20 11.9128 0 

The lines are \r\n-delimited. Could be caused by #45614? Not sure why only a couple of lines get affected.
