Compile failure in UHT with combined multi-line / single line comments

Using a single line comment to immediately follow a multi-line comment closing brace results in an illegible compile errors: "error code: CrashOrAssert(3)"

Workaround:
Include a space between */ and // at the end of the multi-line comment

1. Open UE4 Editor
2. Create a new C++ project w/o starter content
3. Create code class based on actor
4. Add UCLASS() macro above original UCLASS() macro
5. Add mutli-line comment around the second UCLASS() macro
6. Add single line comment immediately following the closing of the multi-line comment
7. Compile

Result:
Compile will fail with error mentioned in description.
