5*
6* Trap to a debugger if the value of the stack pointer has changed.
7*
8* PARAMS
9* None.
10*
11* RETURNS
12* Does not return.
13*
14* NOTES
15* This function is available for iX86 only.
16*
17* When VC++ generates debug code, it stores the value of the stack pointer
18* before calling any external function, and checks the value following
19* the call. It then calls this function, which will trap if the values are
20* not the same. Usually this means that the prototype used to call
21* the function is incorrect. It can also mean that the .spec entry has
22* the wrong calling convention or parameters.
