Interesting, so somewhat the system is triggering an illegal arm64 instruction? Can be that gdb needs somebody telling it to use armhf platform? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707409

qemu isn't involved. We intentionally run armhf builds on an arm64 kernel (with an appropriate personality set) because this allows us to make denser use of our build resources; I don't expect this to change. -- You received this bug notification because you are a member of Ubuntu Bugs, which

Well, LP builders have qemu 2.5, so this might be true for the syscall. However, I appreciate the first point, this is in-line with my expectations and might be solvable by launchpad buildd team admins. Can you please have a deeper look now? thanks! -- You received this bug notification

There is two issues being mixed up here 1) launchpad buildd changes. notmuch build system appears to be confused by the new enviroment. It appears ubuntu has chosen "armhf chroot on arm64 machine" approach, which would mean qemu system call emulation is not involved. if it is - it a buildd

I agree on 384 being getrandom and there are other cases like [1]. I don't know details but would consider the pure lack of the system call support a feature request to upstream qemu. We could add a qemu upstream task here for that FR - in the worst case we are told why we are wrong - opinions?
