[16:51] <b-rad> hi i have a strange build issue, where 32bit failed but 64bit completed. The 32bit failure was due to "stray ‘\1’ in program", but I don't see any such character in a hex editor
[16:53] <cjwatson> Have you tried reproducing the bug locally in e.g. sbuild?
[16:53] <cjwatson> It's very unlikely to be a Launchpad-specific problem.
[16:53] <b-rad> i'll look into setting up sbuild, i just do standard sanity builds for 64bit
[16:53] <b-rad> just weird that for the same code 32bit pukes, but not 64bit
[16:54] <b-rad> and unfortunately where build log says there's a \1 there isn't
[16:55] <cjwatson> Can't say any more without a link to the failure
[16:55] <b-rad> https://launchpadlibrarian.net/435131782/buildlog_ubuntu-bionic-i386.linux_4.15.0-55201907291620.0+mediatree+hauppauge_BUILDING.txt.gz
[16:56] <cjwatson> I suppose stray memory corruption is always a possibility (retrying would confirm whether it's just that), but would be surprising
[16:56] <cjwatson> If it persists beyond that then you probably need to consult a kernel developer for help
[16:57] <b-rad> i guess i'll push rebuild and see, was hesitant to do that without inquiring if this had been seen before
[16:57] <b-rad> as well as get a sbuild docker setup
[17:00] <cjwatson> It's not a familiar problem, no
[17:57] <b-rad> cjwatson, must have been a stray cosmic ray collision, the rebuild succeeded
[17:57] <b-rad> lcy01-amd64-024 was the machine
[21:36] <cjwatson> b-rad: OK, I guess with enough builds going through small probabilities add up
[21:38] <b-rad> i shall be that statistical anomaly
[21:39] <cjwatson> (The machines are ephemeral VMs, so there's unlikely to be much trace left)
[21:39] <b-rad> i saved the build log in case it was desired, but i doubt it would be of any in sight besides the host machine
[21:43] <cjwatson> No, I don't think so, indeed
