[opensuse-buildservice] OBS and PPC64 versus PPC64LE ... sometimes build failures

24 Nov 2017

      Hi,

I've some trouble with building mksh on PPC64 and PPC64LE. Very often
it fails on PPC64 fails with:

  FAIL ./check.t:heredoc-tmpfile-5
         Description:
                 Check that heredoc temp files aren't removed too soon or too late.
                 Backgrounded subshell command with here doc
         unexpected stdout - first difference: line 1, char 1 (wanted 'A', got 'L'
         wanted:
                 A
                 hi
                 B
                 Left overs: *
         got:
                 Left overs: *
                 A
                 hi
                 B

sometimes it works perfect. Also I see sometimes a similar defect on PPC64LE at
exactly the same check of the test suite of mksh.

All build systems seems to be based on qemu/kvm, nevertheless there seem to be
some differences but how to detect those (virt-what does report nothing).
Maybe it depends on the real host on which qemu-system-ppc64 or qemu-system-ppc64le
will be executed.  It could be a defect of qemu based on the hosting system.

Do we have some real PPC64 and/or PPC64LE irons in our build farm or all hosts
based on qemu/kvm?
