I tried to isolate what was running concurrently and found 7 gcc calls. I have set them up to run concurrently in endless loops each. That way they reached a lot of iterations without triggering the issue :-/
I don't know how to continue :-/ But I can share a login to this system and show how to trigger the bug. The following will get you there and trigger the bug usually in 1-2 loops (~4h on average) $ ssh [email protected] $ lxc exec groovy-gccfail bash # cd qemu-5.0/ # i=1; export DEB_BUILD_OPTIONS=parallel=4; while debuild -i -us -uc -b -d; do echo "try $((i++)) complete" >> ~/build.log; done @Doko could you take over from here as I'd hope you know how to force gcc to give you a dump? I imported your key to the system mentioned above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890435 Title: gcc-10 breaks on armhf (flaky): internal compiler error: Segmentation fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-10/+bug/1890435/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
