     Type:  defect            |     Status:  new
 Priority:  major             |  Milestone:  3.6.3
Component:  Default           |    Version:  3.6.2
 Severity:  Unassigned        |   Keywords:
------------------------------+--------------------------
 I am able to build (make) geos on ppc64le architecture but when running
 the test suite (make check), 2 tests are failing.

 The tests are:

 ./tests/ticket/bug398.xml: case1: test1: union(A, B): failed. (0 ms)

 ./tests/general/TestCentroid.xml: case31: test1: getcentroid(A): failed.
 (0 ms)


 I tried it both in Alpine 3.6 and Ubuntu 16.04.3 and in both distros the
 same tests failed.


 The failure log:

 {{{
