Editor crashed while increasing size of string array in the inspector.

Steps to Reproduce:
1. Create a new project.
2. Create a new script.
3. Add following variables to the script:
public string[] a;
public int b = 2;
public int[] c;
4. Attach the script to a GameObject.
5. In the inspector, set string array 'a' size to 2(it can be any value).
6. Add values to the elements of string array 'a'.
7. Now resize string array size as 3.

Actual Result: Editor crashes.

Expected Result : String array should get resized and editor should not crash

Notes:
- Appears on both Mac and Windows
- Appears only when there is a variable defined between two arrays (one should be string array)
- Appears only for string arrays.
- *Increasing string array size also removes data from the corresponding variable (see the attached video-"SideEffects.mp4" for details)
