Comment(by drkirkby):
I can confirm what John found on 't2.math' - this package is now broken on
Solaris 10 SPARC in at least 32-it mode.
This is on my own personal machine, a Sun Blade 1000 with a pair of 900
MHz UltraSPARC III+ CPUs. It runs the very first release of Solaris 10
(March 2005), whereas t2.math runs a quite recent version.
I think we are seeing the problems of working with unstable snapshots. An
updated Pari was working on 't2' a few weeks ago - I posted the list of
test failures above. Since then, the snapshot has been updated, which no
doubt fixes one problem, but creates another. Last I noticed, the upstream
snapshot was being updated three times per day on average. Clearly the
snapshots are not well tested, yet we are using them, and doing the tests
ourselves.
I suggest that we report this, and try to get a fix. But rather than
download the latest snapshot, we just apply the fix we actually need.
Otherwise we have to go thought a lengthly test cycle again. I'm sure it
will be tempting to update to the latest snapshot to get even more bugs
fixed, but how many will be added?
Worth reading is a book by Fred Brooks called The Mythical Man-Month.
Of particular note here is is point that [http://en.wikipedia.org/wiki
/The_Mythical_Man-Month#The_tendency_towards_irreducible_number_of_errors
that in a suitably complex system there is a certain irreducible number of
errors. Any attempt to fix observed errors tends to result in the
introduction of other errors.]
