Package: qemu-user-static
Version: 1.7.0+dfsg-3
Severity: normal
Dear Maintainer,
this seems to be different from #731082 but I might be wrong.
My scripts that create a foreign chroot call ssh-keygen rather at the
end of that process, and that one triggers an "Invalid instruction"
How to repeat:
Create a foreign wheezy chroot for powerpc at /tmp/chroot, make sure
the openssh-client is installed there, copy/link
/usr/bin/qemu-ppc-static into the chroot, then run:
# chroot /tmp/chroot/ /usr/bin/qemu-ppc-static /usr/bin/ssh-keygen
Output:
Invalid instruction

Quite a surprise, the program continues to run and seems to do the
right thing. So it might be just a visual thing, severity left at

Thanks a lot for that deep analysis. Most important thing is to know
no harm is done indeed, so I agree this bug's (or rather feature?)
severity isn't that high.
Let's close this bug report finally (after 11+ years).
Please feel free to reopen it if you think it is incorrect.
Thanks,
