// Bug 1527862: Don't assert that the Debugger drained its job queue unless we

// actually saved the debuggee's queue.

// Put a job in the queue.

Promise.resolve(42).then(() => {});

var g = newGlobal({ newCompartment: true });

var dbg = new Debugger(g);

dbg.onNewScript = script => {};

// Cause an OOM while initializing the AutoDebuggerJobQueueInterruption, so that

// the destructor is run on an uninitialized instance.

//

// A properly initialized AutoDebuggerJobQueueInterruption asserts that the

// debugger left its job queue entry, before restoring the debuggee's job queue

// that it saved when it was initialized. But if OOM interrupts initialization,

// the job queue left on the JSContext is still the debuggee's, which we have no

// reason to expect is empty, so we shouldn't make any assertions about its

// state. The assertion must be conditional on proper initialization (and use

// the correct condition).
