I've had a crash recently occuring to me in which blender hard crashes when I try to either rotate, or pan in the viewport. This only occurs in one scene of mine, which I sadly cannot share, I am working on it for another company.
The odd thing is, blender only crashes in specific layers of the file. So for example, layer 1 is completely fine to do whatever inside, but layer two makes blender crash at an instant when trying to change the viewport through either rotating, panning, or using the shortcut keys to change anything about the view I have.
The problem probably lays in the models I have in each layer, when moving the models to another layer it still consistently crashes there when trying to move the viewport. The model on the crashing layer isn't anything performance-heavy by the way, 8k verts with some basic materials.
I run blender 2.79 on Windows 10 with an i5-6600K, GTX 970, 16GB of RAM, and yes, I've tried the usual, updating drivers and such.
EDIT: I discovered I am fine to move the viewport if I am not actually "seeing" the model, but as soon as it gets into view blender crashes.
