The point/polygon regression tests have started to fail on 32-bit powerpc on Debian Jessie. So far I could reproduce the problem with PostgreSQL 9.4.10+11 and 9.6.1, on several different machines. Debian unstable is unaffected.
The failure looks like this: https://buildd.debian.org/status/fetch.php?pkg=postgresql-9.6&arch=powerpc&ver=9.6.1-2~bpo8%2B1&stamp=1485184696&raw=0 ******** build/src/test/regress/regression.diffs ******** *** /«PKGBUILDDIR»/build/../src/test/regress/expected/point.out Mon Oct 24 20:08:51 2016 --- /«PKGBUILDDIR»/build/src/test/regress/results/point.out Mon Jan 23 15:17:51 2017 *************** *** 125,131 **** | (-3,4) | 5 | (-10,0) | 10 | (-5,-12) | 13 ! | (10,10) | 14.142135623731 | (5.1,34.5) | 34.8749193547455 (6 rows) --- 125,131 ---- | (-3,4) | 5 | (-10,0) | 10 | (-5,-12) | 13 ! | (10,10) | 14.1421356237309 | (5.1,34.5) | 34.8749193547455 (6 rows) *************** *** 150,157 **** | (-5,-12) | (-10,0) | 13 | (-5,-12) | (0,0) | 13 | (0,0) | (-5,-12) | 13 ! | (0,0) | (10,10) | 14.142135623731 ! | (10,10) | (0,0) | 14.142135623731 | (-3,4) | (10,10) | 14.3178210632764 | (10,10) | (-3,4) | 14.3178210632764 | (-5,-12) | (-3,4) | 16.1245154965971 --- 150,157 ---- | (-5,-12) | (-10,0) | 13 | (-5,-12) | (0,0) | 13 | (0,0) | (-5,-12) | 13 ! | (0,0) | (10,10) | 14.1421356237309 ! | (10,10) | (0,0) | 14.1421356237309 | (-3,4) | (10,10) | 14.3178210632764 | (10,10) | (-3,4) | 14.3178210632764 | (-5,-12) | (-3,4) | 16.1245154965971 *************** *** 221,227 **** | (-10,0) | (0,0) | 10 | (-10,0) | (-5,-12) | 13 | (-5,-12) | (0,0) | 13 ! | (0,0) | (10,10) | 14.142135623731 | (-3,4) | (10,10) | 14.3178210632764 | (-5,-12) | (-3,4) | 16.1245154965971 | (-10,0) | (10,10) | 22.3606797749979 --- 221,227 ---- | (-10,0) | (0,0) | 10 | (-10,0) | (-5,-12) | 13 | (-5,-12) | (0,0) | 13 ! | (0,0) | (10,10) | 14.1421356237309 | (-3,4) | (10,10) | 14.3178210632764 | (-5,-12) | (-3,4) | 16.1245154965971 | (-10,0) | (10,10) | 22.3606797749979 ====================================================================== *** /«PKGBUILDDIR»/build/../src/test/regress/expected/polygon.out Mon Oct 24 20:08:51 2016 --- /«PKGBUILDDIR»/build/src/test/regress/results/polygon.out Mon Jan 23 15:17:51 2017 *************** *** 222,229 **** '(2,2)'::point <-> '((0,0),(1,4),(3,1))'::polygon as inside, '(3,3)'::point <-> '((0,2),(2,0),(2,2))'::polygon as near_corner, '(4,4)'::point <-> '((0,0),(0,3),(4,0))'::polygon as near_segment; ! on_corner | on_segment | inside | near_corner | near_segment ! -----------+------------+--------+-----------------+-------------- ! 0 | 0 | 0 | 1.4142135623731 | 3.2 (1 row) --- 222,229 ---- '(2,2)'::point <-> '((0,0),(1,4),(3,1))'::polygon as inside, '(3,3)'::point <-> '((0,2),(2,0),(2,2))'::polygon as near_corner, '(4,4)'::point <-> '((0,0),(0,3),(4,0))'::polygon as near_segment; ! on_corner | on_segment | inside | near_corner | near_segment ! -----------+------------+--------+------------------+-------------- ! 0 | 0 | 0 | 1.41421356237309 | 3.2 (1 row) The 9.4.11 log contains the same point.out diff, but not polygon.out: https://buildd.debian.org/status/fetch.php?pkg=postgresql-9.4&arch=powerpc&ver=9.4.11-0%2Bdeb8u1&stamp=1487517299&raw=0 Does that ring any bell? As Debian unstable is unaffected, it's likely the toolchain to be blamed, but it worked for Debian Jessie before.
