Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
It occurred at the line:
IVideoDriver* driver = device->getVideoDriver();
In the Hello World example it would continue to run if I clicked continue (to ignore the error), but in the other examples it would give me another error shortly after similar to the following:
Unhandled exception at 0x00411c75 in 6.2DGraphics.exe: 0xC0000005: Access violation reading location 0x00000000.
It seemed like a problem with a DLL or something... and... yep, that was it. I had an older version of the Irrlicht.dll in the path before the correct version. Someday I'll learn never to try anything resembling thought when I'm tired.
I hope this post will save someone else the headache it's caused me for the past few minutes.
