Hi, Dear All. I got a very strange problem ,and still can not fix it , just a simple code from TI FFT code

void FFT_TI(short xy[],short n,short w[]) {
    short n1,n2,ie,ia,i,j,k,l,xt,yt,c,s;

    n2 = n;
    ie = 1;
    for (k=n; k > 1; k = (k>>1) )
    {
        n1 = n2;    n2 = n2>>1;        ia = 0;
        for (j=0; j < n2; j++)
        {
            c = w[2*ia]; s = w[2*ia+1]; ia = ia+ie;
            for (i=j; i < n; i = i + n1)
            {
                /*compute Butterfly with inputs xy[i] and xy[l], twiddle factor w[ia]*/
                l = i + n2;
                xt = xy[2*l] - xy[2*i];
                xy[2*i] = xy[2*i] + xy[2*l];
                yt = xy[2*l+1] - xy[2*i+1];
                xy[2*i+1] = xy[2*i+1] + xy[2*l+1];
                xy[2*l] = (c*xt + s*yt)>>15;
                xy[2*l+1] = (c*yt - s*xt)>>15;
            }
        }
        ie = ie<<1;
    }

    //print outputs
    for (j=0; j < n; j++)
    {    printf( " xy[%d]= \t", 2*j );         printf( "%d \t", xy[2*j] );
        printf( " xy[%d]= \t", 2*j+1 );        printf("%d \n", xy[2*j+1]);
    }
}

everytime I tried to debug it, the Code Warrior IDE for StarCore always gives me the following error message:

scc -r "C:\Documents and Settings\victorlxy\My Documents\FreeScale Projecs\test" -g -ge -env "C:\Program Files\Freescale\CodeWarrior for StarCore 3.1\StarCore_Support\compiler" -be -arch sc3400 -c -sc -mod -O3 -cfe -I . -I- -I "..\..\..\..\..\Program Files\Freescale\CodeWarrior for StarCore 3.1\StarCore_Support\compiler\include" -I "..\..\..\..\..\Program Files\Freescale\CodeWarrior for StarCore 3.1\StarCore_Support\compiler\src\rtlib\expanded" -o "test_Data\C_for_SC_Simulator\ObjectCode\main.obj" "C:\Documents and Settings\victorlxy\My Documents\FreeScale Projecs\test\main.c"

Link Error   : link exit status = 2

but the strange thing is that when I changed the compiler settings from "Optimised For Faster Execution Speed" to "Optimized for Smaller Code Size", it will work fine, and the above error message won`t bother me anymore....

but I definitely need to set the compiler to optimize the code for faster execution speed to collect the best possible performance data/....

so anyone can help me in this regard.... thank you so much in advance....
