Bug #12657

Updated by nobu (Nobuyoshi Nakada) over 7 years ago

This is related to Bug #12191. 

 Changing in internal.h:983-985 

 from : 

 ```diff ``` 
 -#define RBASIC_CLEAR_CLASS(obj)          (((struct RBasicRaw *)((VALUE)(obj)))->klass = 0) 
 -#define RBASIC_SET_CLASS_RAW(obj, cls) (((struct RBasicRaw *)((VALUE)(obj)))->klass = (cls)) 
 ``` 

 to: 

 ```C ``` 
 #ifdef __ibmxl__ 
     #define RBASIC_SET_CLASS_RAW(obj, cls) memcpy(&((struct RBasicRaw *)((VALUE)(obj)))->klass, &(cls), sizeof(VALUE)) 
 #else 
     #define RBASIC_SET_CLASS_RAW(obj, cls) (((struct RBasicRaw *)((VALUE)(obj)))->klass = (cls)) 
 #endif 

 #ifdef __ibmxl__ 
     #define RBASIC_CLEAR_CLASS(obj)          memset(&(((struct RBasicRaw *)((VALUE)(obj)))->klass), 0, sizeof(((struct RBasicRaw *)((VALUE)(obj)))->klass)) 
 #else 
     #define RBASIC_CLEAR_CLASS(obj)          (((struct RBasicRaw *)((VALUE)(obj)))->klass = 0) 
 #endif 
 ``` 

 This allows for ruby to build using XL compiler. Otherwise build fails because of ANSI aliasing issues.
