fscanf c - segmentation fault

Question

the problem is to read from a file(the files are read in command line, linux) a character, then a tic tac toe matrix. then i want to return what i read (just a small test). i got segmentation fault. from what i've searched, the problem was a new line, so i consumed it with dummy. the same answer came. i checked if the files are opened correctly. i'd appreciate some help, thank you.

int main(int argc, char *argv[])
{
     FILE *src, *dest;
     int i,j;
     char s[2];
     char* dummy;
     char* m[3][3];
     src=fopen(argv[1],"r");
     dest=fopen(argv[2],"w");
     fscanf(src,"%s",s);
     fscanf(src,"%s",dummy);    
     for(i=0;i<3;i++)
     {
         for(j=0;j<3;j++)
         {
              fscanf(src,"%s",m[i][j]);
         }
         fscanf(src,"%s",dummy);
     }
     for(i=0;i<3;i++)
         for(j=0;j<3;j++)
             fprintf(dest,"%s",m[i][j]);

fclose(src);
fclose(dest);
return 0;
