[Critical] Editor crashes when #line directive is misplaced outside shader's block of code

Shader System


How to reproduce:
1. Create a new 3D template project
2. Create a new Standard Surface Shader and open it
3. Add "#line 0" directive right after the shader's code ending bracket
4. Save the shader and focus the Editor

Expected result: The editor throws an error due to invalid input once the shader is recompiled
Actual result: The Editor crashes

Reproducible with: 2018.4.26f1, 2019.4.6f1, 2020.1.1f1, 2020.2.0a20

1. When 2018.4.26f1 version is used, a crash pop-up is thrown after the shader is recompiled, however, the Editor does not actually crash and can be used afterward. This happens the only after the first shader recompile. Subsequent changes to the shader do not lead to a thrown crash pop until the Editor is reloaded(Track_1265143_V1)

  1. Resolution Note (2020.2.X):

    This is an edge case which is, unfortunately, very difficult to fix in the current system.
