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