_DATA_GROUP_ Overflow error

Supreet Suresh

Hello all,
i have DECT handset based on 8051 controller..
and i also have an application software running on it.

I am planning to run this software in debug mode in Keil IDE itself, so that i can run some keypad simulators interfaced through AGSI driver interface.

SO i commented a funtion call which internally declares some local variables. then the linker gives me this error.. if i uncomment the function call ... every thing works fine...

i am using SMALL memory model...

can anyone please suggest me the reason for it.

error is

*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: DATA SEGMENT: _DATA_GROUP_ LENGTH: 000050H

thanks,
supreet

    Thanks for the reply,

    i will give an example of my problem,

    Main()
    { dummy_func1(); //dummy_func2(); dummy_func3();
    }

    dummy_func2()
    { unsigned char a; unsigned int b; /* some code here */
    }

    So if i do something like this then the linker error comes..
    if i remove the commenting of function call dummy_func2(), then everything works fine..

    The question i am asking here is, if i am not calling the function dummy_func2() then i am actually not declaring two variables , so it actually has to reduce the DATA memory occupied...

    But exactly opposite thing happens, when i call the function and two variables are decalred the Overflow error doesnt come...

    Thanks,
    Supreet

    PS: MY application is not as simple, i just gave an example of the problem :)
