Bug Description

Encountered below crashes in qemu 3.10 arm
Also have raised the same in golang groups. But seems like in ARM32 hardware, the below commands works fine, only in qemu if crashes.

Need some pointers to narrow down

Please see log below.

Hi; we very recently fixed a QEMU bug which causes crashes like this for Go binaries running under QEMU's linux-user mode. The fix is in the v4.1.0-rc3 we've just put out and will be in the final 4.1.0 release. Could you retry with that and see if it fixes your problem, please?

I suspect you're not using the new version of QEMU in your test. The 'go' binary will fork and exec other go binaries, and Linux binfmt-misc will use the system QEMU binary to run those, even if you were running the top level 'go' binary with the newer QEMU you've built.

For Ubuntu this means you need to put the new QEMU binary into /usr/bin/qemu-arm-static. (Probably "cat /proc/sys/fs/binfmt_misc/qemu-arm" will tell you what interpreter binary it uses. It will also have a "flags:" line -- if this includes 'F' for fixed then you will have to take further measures beyond just copying the new QEMU binary into place, because it means the kernel opens the interpreter binary very early, rather than only on-demand, so it will have effectively cached the old version. I'm not sure how you get it to forget about the old version and re-open the new version.)

Thanks @pmaydell, I missed to check binfmt qemu version. I checked in qemu 4.0.93 and I don't issue any issue.

Thanks for retesting! (We haven't quite got 4.1.0 out of the door yet, so I'll just move this bug to 'fix committed' for the moment; we'll update it back to 'fix released' next week.)
