I observed, however, that one of them held somewhat aloof, and though he seemed desirous not to spoil the hilarity of his shipmates by his own sober face, yet upon the whole he refrained from making as much noise as the rest. This man interested me at once; and since the sea-gods had ordained that he should soon become my shipmate (though but a sleeping-partner one, so far as this narrative is concerned), I will here venture upon a little description of him. He stood full six feet in height, with noble shoulders, and a chest like a coffer-dam. I have seldom seen such brawn in a man. His face was deeply brown and burnt, making his white teeth dazzling by the contrast; while in the deep shadows of his eyes floated some reminiscences that did not seem to give him much joy. His voice at once announced that he was a Southerner, and from his fine stature, I thought he must be one of those tall mountaineers from the Alleghanian Ridge in Virginia. When the revelry of his companions had mounted to its height, this man slipped away unobserved, and I saw no more of him till he became my comrade on the sea. In a few minutes, however, he was missed by his shipmates, and being, it seems, for some reason a huge favourite with them, they raised a cry of "Bulkington! Bulkington! where's Bulkington?" and darted out of the house in pursuit of him.

As seen below, "message" is the culprit. After exception (1) occurs, all the data members of NativeMessage are zero. Even the point is initialized. After exception (2) occurs, the external dll crashes and it brings down your app. I have tried using GC.KeepAlive(message); without luck.

It's very important to specify 'ref' on the MENUITEMINFO otherwise on Windows 7 32-bit user32.dll will crash with the error text 0a9e372d3b4ad19135b953a78882e789. However, Windows 8.1 64 bit it works with or without the 'ref' keyword. Tested both using NET40.

- Various sites declare OLECMD.cmdf as UInt64. For me this crashes IE7 just after my QueryStatus() method is called, but declaring it as uint works fine. This seems correct given the MSDN definition as a DWORD - http://msdn.microsoft.com/en-us/library/ms690534%28VS.85%29.aspx

In contrast, if you are trying to do managed-debugging (instead of just write a native debugger in C#), you need to use the managed debugging APIs (ICorDebug) instead of the native debugging APIs here.
