Upload your core dumps and crash logs directly to github. Having to visit a clunky google drive page that takes ages to load here is not helping.

Sorry... github say it's too big, must smaller than 25MB Is there any other way to upload this to GitHub?

I don't think that's necessary, there's only one call to the item = operator in that function. https://github.com/CleverRaven/Cataclysm-DDA/blob/576d6396cc205edb38a8eb63f9c76d8eb35cfdc4/src/vehicle.cpp#L7636-L7638

I assume that the base part accessed from the parts vector is invalid, which means that either something really fucky happened or (more likely) the cached index of vp.fake_part_at was invalid. If that is the case, knowing it crashes here doesn't help, we'd need to know when it became invalid and why.
