podman build --jobs 4(?) : panic: runtime error: invalid memory address or nil pointer dereference #10535
Description
This is a one-off. Only one instance, no reproducer, am filing as a placeholder in case I see it again:
# $ podman build --no-cache --jobs 4 -t derived-mt -f /tmp/podman_bats.JKqL7z/build-test/Containerfile2 /tmp/podman_bats.JKqL7z/build-test
# STEP 1: FROM quay.io/libpod/alpine AS final

# panic: runtime error: invalid memory address or nil pointer dereference
