Hello All!
Recently PSPP started to fail passing the tests. At least latest 1.0.1
version is affected but I'm certain previous versions are affected as
well. Turned out that the following script has different output on
PPC64 / PPC64LE arches:
DATA LIST FREE/a b c.
VARIABLE LABEL a "hi there".
SORT VARIABLES LABEL.
DISPLAY NAMES.
SORT VARIABLES LABEL (D).
DISPLAY NAMES.
On x86_64 machine (
https://koji.fedoraproject.org/koji/getfile?taskID=21983571&volume=DEFAULT&…
):
+ ./src/ui/terminal/pspp -O format=csv sort-variables.sps
Variable
b
c
a
Variable
a
c
b
On PPC64 ( https://koji.fedoraproject.org/koji/getfile?taskID=21983574&volume=DEFAULT&…
) or on PPC64LE (
https://koji.fedoraproject.org/koji/getfile?taskID=21983572&volume=DEFAULT&…
):
+ ./src/ui/terminal/pspp -O format=csv sort-variables.sps
Variable
c
b
a
Variable
a
b
c
Unfortunately I'm not very well familiar with PSPP internals to
pinpoint exact location where it fails, so I've got stuck. I can't
reproduce it on the PPC64 machine ( ppc64-test.fedorainfracloud.org )
with the following packages:
glibc-2.24-9.fc25.ppc64
gcc-6.4.1-1.fc25.ppc64
if compiled with these ones PSPP produces the same output as if it
runs on x86_64.
I can 100% reproduce it in Koji with the following packages :
glibc-2.26.90-15.fc28
gcc-7.2.1-1.fc28
