Even more so. With my tool chain the line that reports the failing
address is impossible.

[ 73.034423] RIP: 0010:copy_siginfo_from_user+0x4d/0xd0

With the supplied configureation my tool chain only has 0x30 bytes for
all of copy_siginfo_from_user. So I can't even begin to guess where
in that function things are failing.

Any additional information that you can provide would be a real help
in tracking down this strange failure.

Thank you,
Eric Biederman
