What do the details of an APPCRASH message mean?
<p>I am experiencing an APPCRASH from my C# application.  The Runtime gives an error message of "This application has requested the Runtime to terminate it in an unusual way".  Then, when I click okay I get a "MyApplication has stopped working" message with the usual "check online for a solution", "close program" and "debug program" options.  When I click "additional details" I get the APPCRASH signature, with lots of additional information.  Some of it is human readable, some of it is just hex numbers.  The "Exception Code" is 40000015.  There are also lines of "Additional Information".  My question is: does anyone in the universe know what the information in an APPCRASH message means?</p>

<p>It seems like the message was meant to be read by someone who can divine a cause from it.  When searching for answers I found a lot of people posting messages formatted exactly the same.  Unfortunately, I have found no explanations of what this information means.</p>

<p>Also, I have tried the "Debug Program" option, but it is unhelpful.  It just puts me in system dlls with none of my code anywhere up the call stack.  I've investigated, and the error doesn't occur in this system code.</p>

<p>The APPCRASH message named another dll as the "Fault Module" (this code uses a lot of external dlls), and the fatal error probably occurs there. But that information isn't very helpful because I need to find the place in my code that makes a bad call to the external dll (or puts it in a bad state).  Sadly, when I say "my code" I just mean the code that I'm working with.  It's a huge codebase written by several dozen people over a couple years, so I can't just guessing places that might make the fatal call.  That's why I was hoping to divine more information from the APPCRASH message.  That's also why I'm being very stingy with details.  The whole thing is all very proprietary with lots of red tape.  That's also why I haven't posted the APPCRASH message contents.</p>

<p>To be clear, I am not asking you to debug my problem for me.  I have no way of giving you a reproducible case of the error, and I'm not asking anyone to tell me the cause of the error in my specific case.  I just want to know how to interpret those hex numbers, and I haven't been able to find any documentation.</p>
