Subject: gmp-ecm: 7.0 regresses on 32 bit platforms

Date: Mon, 27 Jun 2016 08:33:06 +0200

Package: gmp-ecm
Version: 7.0.1+ds-2
Severity: important

Hello,

Since version 7.0, gmp-ecm fails on i386 and armhf (the two 32 bit
architectures that Ubuntu runs tests on):

  http://autopkgtest.ubuntu.com/packages/g/gmp-ecm/yakkety/i386/
  http://autopkgtest.ubuntu.com/packages/g/gmp-ecm/yakkety/armhf/

64 bit still works, like

  http://autopkgtest.ubuntu.com/packages/g/gmp-ecm/yakkety/amd64
  http://autopkgtest.ubuntu.com/packages/g/gmp-ecm/yakkety/ppc64el

I haven't yet found out what to search for in the log [1] to see the
actual error. There is no "fail" in the upstream output, and all the
"error" hits that I checked are also present in the amd64 log, i. e.
they are expected error messages triggered by the tests. I hope you
have some more familiarity with the test output and know what to look
for.

We don't run 32 bit tests on Debian, so this doesn't appear on
https://ci.debian.net/packages/g/gmp-ecm/.

I'm setting severity "important" as this package may be a building
block for security mechanisms (even though nothing in Debian currently
uses it).

Thanks,

Martin

Hello again,

sorry, this evaded me before, here it is:

Same error on armhf and i386, and this does not happen on 64 bit.

I can reproduce this in sid with autopkgtest's schroot runner, so it's
not specific to Ubuntu or LXC/LXD/QEMU:

  autopkgtest gmp-ecm -- schroot sid-i386

Thanks,

Martin
