| 43 // 4810578: varargs unsafe on 32-bit integer/64-bit pointer architectures | |
| 44 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in | |
| 45 // system header files. On 32-bit architectures, there is no problem. | |
| 46 // On 64-bit architectures, defining NULL as a 32-bit constant can cause | |
| 47 // problems with varargs functions: C++ integral promotion rules say for | |
| 48 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a | |
| 49 // varargs function it will remain 32-bits. Depending on the calling | |
| 50 // convention of the machine, if the argument is passed on the stack then | |
| 51 // only 32-bits of the "NULL" pointer may be initialized to zero. The | |
| 52 // other 32-bits will be garbage. If the varargs function is expecting a | |
| 53 // pointer when it extracts the argument, then we may have a problem. | |
| 54 // | |
| 55 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0. | |
