101 * Trap to a debugger if the value of the stack pointer has changed.
110 * This function is available for iX86 only.
112 * When VC++ generates debug code, it stores the value of the stack pointer
113 * before calling any external function, and checks the value following
114 * the call. It then calls this function, which will trap if the values are
115 * not the same. Usually this means that the prototype used to call
116 * the function is incorrect. It can also mean that the .spec entry has
117 * the wrong calling convention or parameters.
