I am not sure if it is still true, but Keil did not use the stack for data.

1) fill the stack with a specific number. Periodically read the stack area to see how far it has been used.
2) the stack works down toward the variable memory. Reserve the last byte (or two) of memory. If it changes you know the stack has overflow.

Neither of course can be 100% reliable

      malloc() on 8051?!?            01/01/70 00:00      
         Yes.            01/01/70 00:00

         You are right            01/01/70 00:00      
   Probably this miight be happening            01/01/70 00:00      
      This sounds as a reason but...            01/01/70 00:00      
         asm            01/01/70 00:00      
            I think the same            01/01/70 00:00      
               the asm will maybe help            01/01/70 00:00      
                  Assembler codes            01/01/70 00:00      
                     Michal, you are cheating! :-)            01/01/70 00:00      
                        This was the reason :)            01/01/70 00:00      
                     ... but it's easy to do it in C :-)            01/01/70 00:00      
                        I dont trust to any any any compiler :)            01/01/70 00:00      
            Stack overflow?            01/01/70 00:00      
               I think this will be complicated            01/01/70 00:00      
                  1 of 2 ways            01/01/70 00:00      
                     Thx            01/01/70 00:00      
         The Compiler does not protect you            01/01/70 00:00      
            Like SDCC...            01/01/70 00:00      
               Better?            01/01/70 00:00      
                  option --main-return            01/01/70 00:00      
                     SDCC function startup code            01/01/70 00:00      
                        use a cookie near the end of the stack?            01/01/70 00:00      
                           rock bottom            01/01/70 00:00      
                           Why only 0xF8?            01/01/70 00:00      
                              paranoia!)            01/01/70 00:00      
               also Keil?            01/01/70 00:00      
            I have while(1) loop in main()            01/01/70 00:00
