So, first things first. The file has clip start and end of 0.001 in the viewport. In other words, you are expected to not see anything when outside camera view. How did this file come to be?

Secondly, the crash itself was introduced on 267e816b9a.

@dfelinto I was playing with a depth of field idea in grease pencil and this is why I had these view values when I discovered the assert. You are right, the cube is invisible by viewport clip values, but the assert is really annoying filling console with hundreds of messages.

@antoniov You should try building with WITH_ASSERT_ABORT (advanced CMake option). Asserts are not to be dismissed as harmless prints. They are asserts for a reason, they are to crash your Blender at an early stage, so "you" can inspect what is going on.

@dfelinto Thanks for the info. I knew that asserts are important and must be something to verify during development, but I didn't knew the Cmake flag.
