When I build snapd with -buildmode=pie in artful on i386 and then "snap install core" on a fresh system the system panics. Building without "-buildmode=pie" works fine.

When I build snapd with -buildmode=pie in artful on i386 and then "snap install core" on a fresh system the system panics. Building without "-buildmode=pie" works fine.
See also https://forum.snapcraft.io/t/artful-i386-panics/
Here is the panic log:
