Version: 4.17.2

Platform Windows 10 x64

Description:  
If you add a BP interface to a BP widget, that contains a function which has the same name as one of the widget’s variables. Then the editor will crash once you click on compile, without Warning.

Repro Steps:

- Create a blank project
- Create widget with a variable called “Test”.
- Create a blueprint interface with a function called “Test”.
- Add the interface to the widget and click compile.

Partial crash output:

> Fatal error:  
> [File:D:\Build++UE4+Release-4.17+Compile\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp]  
> [Line: 2289] Objects have the same
