Greetings.

In the org file below, the first babel block will evaluate just fine,
while the second will signal "End of file during parsing". The
difference is the opening bracket "[" in output.

I think am running the most recent stable version:
Org mode version 9.3.7 (release_9.3.7-4-gba6ca7)

Thanks for any ideas.
