[1, {a = 1}].join(",") prints its located error and then the interpreter crashes (a double free in the join error path). Found by the self-hosted interpreter.

join() on a list with a non-text entry now stops with its located error and no crash (branch tickets-a, 4906c31b).
Test:
1. Run a file with console.log([1, {a = 1}].join(",")).
2. You see the join error, exit code 1, no crash trace.
