signal 11 for 'conftest' && poudriere jails

[Matthias Apitz]

While running poudriere jails on a very recent CURRENT:

FreeBSD jet 13.0-CURRENT FreeBSD 13.0-CURRENT #1 r349041: Sat Jun 15 07:45:13 CEST 2019     guru at jet:/usr/obj/usr/src/amd64.amd64/sys/GENERIC  amd64

I see messages about signal 11 for 'conftest'. The uid 65534 (nobody)
let me think in poudriere, because there is nothing else running on this
box:

What does this mean? What is 'conftest' at all?
