Nested comments are not parsed correctly by UHT when a second UClass is declared

Using nested comments when also declaring a second UClass in the same header file causes the UHT to have issues when parsing, resulting in a crash of UHT.

1. Create a new code project
2. Add a C++ class based off the Actor class
3. Inside of the class declaration in the .h file, add the following lines:

   /*
   /*
   */
   

4. Below the class declaration, add the following lines:

   UCLASS()
   class PROJECTNAMEHERE_API UThisClassIsDetectedAsExpected : public UObject
   {
   	GENERATED_BODY()
   };
   

   Where PROJECTNAMEHERE matches your project name in all caps

5. Attempt to compile the project
   Result: UHT crashes
   Expected: UHT should be able to parse this correctly.
