95 // 4810578: varargs unsafe on 32-bit integer/64-bit pointer architectures
96 // When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in
97 // system header files. On 32-bit architectures, there is no problem.
98 // On 64-bit architectures, defining NULL as a 32-bit constant can cause
99 // problems with varargs functions: C++ integral promotion rules say for
100 // varargs, we pass the argument 0 as an int. So, if NULL was passed to a
101 // varargs function it will remain 32-bits. Depending on the calling
102 // convention of the machine, if the argument is passed on the stack then
103 // only 32-bits of the "NULL" pointer may be initialized to zero. The
104 // other 32-bits will be garbage. If the varargs function is expecting a
105 // pointer when it extracts the argument, then we have a problem.
106 //
107 // Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0.
108 //
109 // Note: this fix doesn't work well on Linux because NULL will be overwritten
110 // whenever a system header file is included. Linux handles NULL correctly
111 // through a special type '__null'.
