Hi guys, I've encountered lots of first-chance exceptions like this:

First-chance exception at 0x16897232 in myApp_DEBUG.exe: 0xC0000005: Access violation writing location 0x00000000
And when I tagged the "Thrown" field in the Access Violation Exception option, it breaks and dumped this call stack:

Now the problem is all items inside of the call stack is from compiled .dlls and there's no source code whatsoever in all of them. Thus I couldn't get the real problematic line of code in my application. So, now I don't have any clue as to where to start debugging. Do I have to do a disassembly?Unfortunately my assembly knowledge is somewhat lacking (so I guess even if I did some disassembly, it won't do any good). (T.T)

The funny thing is, in the release version it would do fine most of the time. But still it would randomly crash with an exception error. I know that a first-chance exception is not necessarily a bug, but if there's a lot of them I think it is a bug.

Can anybody help me? Thanks a lot in advance guys.
