Hello, With ppl-0.10.2, several Mac OS X fink users (including myself) have observed the following single test failure on 10.5 and 10.6, using Apple's gcc-4.2, arch i686-apple-darwin{9,10}, with thorough tests enabled:
/usr/bin/grep -E "^Optimum value: " ../../../demos/ppl_lpsol/expected_mpz

Most fink users that reported this have built ppl against gmp-4.3.2. I tested a build against gmp-5.0.1 and got the exact same result on i686-apple-darwin10.
However, the same set of tests (check thorough) pass *cleanly* on powerpc-apple-darwin8 apple-gcc-4.0.1 (ppl-0.10.2 using gmp-4.3.2), which took over 4 days to run.
Has anyone else observed this failure on this version/configuration? How severe is this test failure?
(Unrelated note: ppl-0.11's tests run cleanly on i686-darwin10.)
