Comment 6 for bug 1962170

Hum, it seems your patch makes sense and should work on most arch. I saw Michael did an upload with this: https://launchpad.net/ubuntu/+source/adsys/0.8ubuntu1
But it’s failing only on ppcel64: https://launchpadlibrarian.net/588289907/buildlog_ubuntu-jammy-ppc64el.adsys_0.8ubuntu1_BUILDING.txt.gz and passing on other architectures.

The issue may be related to the signal installed on libsmbclient: https://github.com/ubuntu/adsys/blob/main/internal/smbsafe/smbsafe.go#L4. This workaround is the only reason of smbsafe (you can’t then exec concurrently subprocesses without cleaning up those signals and the library is doing that at every smb call on your behalf).
Another idea is that stderr is not allocated for whatever reason https://github.com/ubuntu/adsys/blob/main/internal/testutils/samba.go#L38 but why only on ppcel64?

I reastically won’t have the time this week with the sprint to look at this. I hope this gives some hints if you need urgently to have it fixed before next one.
