[Robin Templeton [:terpri]]

See attached try log; the following programs also cause Ion crashes in the JS shell when both BigInt and Ion are enabled:

for (var i = 0; i < 2000; i++) { console.log((function(){return 1n;})()); }
for (var i = 0; i < 2000; i++) { console.log((function(){return BigInt(1)?1:0;})()); }
