It's not on the download page. It looks like only 2.5.1 is available at this URL:
http://flintlib.org/flint-2.5.1.tgz But this won't help as the test and associated function that are causing the failure you reported were added between 2.4.5 and 2.5.1. So you will have to go back to 2.4.5 to get a working version presumably. Having said that, 2.5.0 should have passed, and I don't think these were added in 2.5.1, so it's strange that it is failing for you. It could be a miscompilation. I did have a report that it fails on MIPS64 and after staring at it for a long time I wasn't able to determine why. I suspect a bug in some version of gcc at this point. I did fix a bug for this function when built against GMP and not MPIR, but this fix is already in trunk. This seemed to fix the problem for MIPS, but then a number of issues vanished there mysteriously upon recompilation. I also valgrinded the test and did lots of other testing to try and find a real bug in the function but came up with nothing. Bill.
