I've had to bin the build environment at work due to the disk running out of space and the one at home went poof when the SSD it was on croaked. I haven't had the time yet to get it up again on the replacement. Anyway, if my hunch that 5.22.3 was not running into this issue is correct, then 2.7.0 was the last released Cygwin version this test was passing for. I might try to get that running on of my home machines again, but I can't really spend all that much time on it for the foreseeable future unfortunately.
