build - Invalid parameter passed to C runtime function.

Not sure if this is normal or related to something in the source for building but when debugview is open you see a bunch of the subject messages when running build.

this is an older ddk but thought I’d mention it in hopes of a definite answer so others searching find it as well.

This might be an exception handler that catches a null pointer exception or something like that. Check KdPrint or DbgPrint parameters.
