Hi Steve, thanks for the bug report and your patch. From my point of view this is a bug in the compiler if the test suite does not pass on the ppc64el architecture with -O3 optimization settings on Ubuntu. However, the problem seems still to be there when 1.2.0-4 was compiled on 22nd of May:
https://launchpad.net/ubuntu/+source/pspp pspp still fails on ppc64el and riscv64 on ubuntu without the patch, i.e. with -O3, while it works on Debian: https://buildd.debian.org/status/package.php?p=pspp I think I will include your patch. Friedrich
