'illegal hardware instruction' / core dump on Node v0.10.18

[msiebuhr]

var g = require('node-gc');

g.on('scavenge', function (i) { console.log('scavenge', i); });
g.on('marksweep', function (i) { console.log('marksweep', i); });

for (var j = 0; j <= 1000; j += 1) {
    var x = new Array(10000);
    for (var i = 0; i < x.length; i += 1) { x[i] = i; }
    for (var i = 0; i < x.length; i += 1) { delete x[i]; }
    process.stdout.write('\r' + j);
}
console.log('\ndone');

Executing it on my local machine always yields

1000
done
scavenge { duration: 18, heapBefore: 5084096, heapAfter: 4965976 }
zsh: illegal hardware instruction (core dumped)  node ./gc-test.js

If I copy/paste it into an interactive Node-session, it dies with the same message at the same point.
