I have encountered this (in the JIT testsuite, and actually added a work-around to the JIT test harness for Darwin). Don't recall whether I got to the bottom of where the extra \r was coming from. expect is one of my least favourite codes to work on - it's such a maze of conditional code - however I do publish a version with some Darwin fixes (although TBH I believe most of those have been pulled into the Apple version - so it might not be so relevant on newer OS versions). https://github.com/iains/darwin-expect
