+// Bug 1475669 - Cross-compartment dependent promises.
+
+// Create a promise in realm 1.
+let g1 = newGlobal({newCompartment: true});
+let p1 = new g1.Promise((_resolve, _reject) => {});
+
+// Add a dependent promise in realm 2.
+let g2 = newGlobal({newCompartment: true});
+let p2 = g2.Promise.prototype.then.call(p1, g2.eval(`value => {}`));
+
+// Use debugger to find p2 from p1.
+let dbg = new Debugger;
+let g1w = dbg.addDebuggee(g1);
+let g2w = dbg.addDebuggee(g2);
+let dependents = g1w.makeDebuggeeValue(p1).promiseDependentPromises;
+assertEq(dependents.length, 1);
+assertEq(dependents[0], g2w.makeDebuggeeValue(p2));
