102 // 4810578: varargs unsafe on 32-bit integer/64-bit pointer architectures | |
103 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in | |
104 // system header files. On 32-bit architectures, there is no problem. | |
105 // On 64-bit architectures, defining NULL as a 32-bit constant can cause | |
106 // problems with varargs functions: C++ integral promotion rules say for | |
107 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a | |
108 // varargs function it will remain 32-bits. Depending on the calling | |
109 // convention of the machine, if the argument is passed on the stack then | |
110 // only 32-bits of the "NULL" pointer may be initialized to zero. The | |
111 // other 32-bits will be garbage. If the varargs function is expecting a | |
112 // pointer when it extracts the argument, then we have a problem. | |
113 // | |
114 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0. | |
