It seems likely it ran out of RAM given it was killed. Please include the full build.log.
I doubt it. I do not see any messages about killed process in any of the system logs. It rarely happens that the compiler complains about a non-existing instruction just before being OOM-killed. The complaint about a non-existing instruction and going out of memory could be two manifestations of the same bug. network_handler.cc is a relatively small file. Will attach the log.
Created attachment 757510 [details] Build log
(In reply to i.hamsa from comment #3) > Created attachment 757510 [details] > Build log This still almost certainly seems like OOM or "pre-OOM". Every time I've seen failures like this, it's when memory pressure is extremely high and the OOM killer either got invoked or was about to get invoked. The "2GB per job" thing is only rough and I'd try again with -j5 or -j6, maybe even lower if your system is in active use. your emerge --info shows 11GB free, hence at most you should be using ~ -j5 or lower. Please try again with a lower job count. I do understand your point, but I've _only_ ever seen it in situations like I described
The build fails even with -j2.

My bad. I did the `ebuild compile` command instead of `emerge` as I didn't want to run a massively long build again just to discover that it fails near the end. I'd rather reuse already built objects. But at this stage `-j7` was already embedded in the generated build script, hardcoded, and no environment variable had any effect. I had to edit the generated script and replace `-j7` with `-j2`, then it worked.
