Hi Niels (also also Stefan, who replied offline),
I tried changing the order of the setters, but that did not appear to make a difference. I also tried calling the setter methods instead of setting the ivars:
dateFormatter.timeStyle = NSDateFormatterMediumStyle;
However, I'm still getting the incorrect format. The code in NSDateFormatter seems fine to me, too (this is the 1.24.8 codeline). But I still get:
dateStr = 20010102 09:00 AM, refStr = Jan 2, 2001, 9:00:00 AM
I will keep digging into it.
Thank you for the help so far,

I was under the impression that that problem had been fixed -- but maybe there's a bug still hiding in there...

I updated my build flags to signal that libicu should be used, and I verified with print statements that NSDateFormatter's GS_USE_ICU variable is set to true.

I tend to think libicu is not the problem, because it runs a lot of internal tests on the udat_format function, which is what NSDateFormatter is calling, and I've confirmed that the format tests pass when run within libicu.
