- This issue appears on Windows and OSX
- This issue appears on Standalone, Android, and iOS
- With Mono, everything works fine
- BugRepro is unsafe C# code that contains an array of pointers
- I believe the issue is that the field type generated when accessing the array of pointers is of type "intPtr_t", when it should be of type "ExampleStruct*"

Reproduced on Unity 2017.2.3p4, 2017.3.2f1, 2017.4.11f1, 2018.1.9f2, 2018.2.8f1, 2018.3.0b2 and 2019.1.0a1
