Crash (assert/check fail) in RapidYAML if the input is a YAML stream #1148

Open johnbartholomew opened 7 months ago

johnbartholomew commented 7 months ago

While trying to reproduce #1147 I hit this assert/check-fail (building with Makefile at cb18fec3721375ddfc938cb4831835ec06c64d81)

❯ ./jsonnet -e 'std.parseYaml("1\n---")'
third_party/rapidyaml/ryml_all.hpp:22998:check failed: !m_tree->is_stream(id)
