     A stack probe is a short routine called on entry to a function.
     The probe verifies that space exists in the program stack in which
     to allocate local variables. The stack probe is called at every
     entry to a function in your program.
 
     Ordinarily, the stack probe routine generates a stack overflow
     message when the required stack space is unavailable. When stack
     checking is turned off, the stack probe routine is not called.
     Stack overflow can then occur without an error message being
     generated.
