Hi Paul, In this case, no reason at all. 1.42 is the version that comes prepackaged for Ubuntu, so that's what's I had installed. However, this is just a small academic project, so there was really no barrier to downloading 1.45, dumping it into our source tree, and pointing the build at it. On the other hand, I have worked in a large development organization which was quite conservative about upgrading to the newest version of any library or tool. Upgrades take time, and if they temporarily break someone's setup (or even a whole team's!) they can consume a huge number of man-hours. Even worse if the new version brings a new and unknown bug with it. So, those managing our projects tended to be cautious about upgrades. We'd use old versions of libraries, old compilers, everything. We were usually a couple of years behind in our boost version, and our compilers were quite a bit older than that. As long as it worked, we wouldn't touch it until someone could make a good case for the benefits of upgrading outweighing the risks. In the case of this bug, such questions as "Do you *have* to use the boost::math special functions? How much effort would it take to just roll our own? Does the new version bring in any known regressions? How long has the new version been 'in the wild,' and how well is the library vetted in general?" Of course I can only speak from my own experience - I have no idea if such practices are common, but hopefully this is the sort of information you were looking for :) Thanks, -Gabe On Mon, Jan 3, 2011 at 12:51 PM, Paul A.

Further experiments show that the issue is present in boost 1.42, but fixed in boost 1.45. Sorry for the noise :)
No problems - glad you have got over this hurdle.
But I'm curious to know why you are still using 1.42.
And also how you found the 'solution'.
(This is in no way a criticism, I'm just trying to understand the barrier that users face, or feel, to using the latest version).
Paul
