This crash occurs when you create a landscape, then create and save a material.
Note The crash does not occur unless a landscape was created first
I came across a couple of crashes revolving around shader compiling manager. I came across UE-39977 a couple of times, but this is the first we have seen this callstack. I also came across some other bugs doing the same kind of saving and painting, working with materials etc, but was never able to get a repro. Those crashes can be found here:

Not sure if they are related, but was encountered performing the same actions.
This is also a Regression since it does not occur in 4.14.2
Result: The editor crashes
Expected Result: The material is saved and the editor dies not crash
