VBoxSVC crash when calling IPerformanceCollector.SetupMetrics

[Ivo Smits]

I accidentally discovered two (very similar) ways to crash VBoxSVC on Windows using the VirtualBox COM API:

1. Call IPerformanceCollector.SetupMetrics and pass an empty array for aObjects
2. Call IPerformanceCollector.SetupMetrics and pass an array containing a reference to an IHost object for aObjects (this is mentioned in the SDK doc as valid)

Testcase in C#:

VirtualBoxClientClass vboxclient = new VirtualBoxClientClass();
vboxclient.VirtualBox.PerformanceCollector.SetupMetrics(new String[] { "*" }, new Object[] { }, 1, 1);
vboxclient.VirtualBox.PerformanceCollector.SetupMetrics(new String[] { "*" }, new Object[] { vboxclient.VirtualBox.Host }, 1, 1);

Please reopen if still relevant with a recent VirtualBox release.
