Short description
I tried to compile the policy in WASM with the optimize > 0 flag, but it caused a panic.
Steps To Reproduce
❯ cat <<EOF > example.rego
package test
import rego.v1
deny if true
EOF
❯ opa build -t wasm -e test/deny example.rego -O 1
panic: runtime error: index out of range [0] with length 0
