[ts-7000] strcmp function is generating segmentation fault

["cspin_2001" <>]

For some reason the strcmp function generates a segmentation fault 
when I run this code on the TS-7260. I am using the crosstools to 
compile it. Has anyone else had this problem. Any ideas how to fix 
it.

Thanks 
Charlie

void gps_Capture()
        {
        char bufcopy[512], temp[512];
        int res,bytes;
        char gpapb[] = "$GPAPB", gpgll[] = "$GPGLL";
        char *token = NULL;
        ioctl(fd2,FIONREAD,&bytes);
        if (bytes > 0 )
                {
                res = read(fd2,gpsbuf,512);
                gpsbuf[res]=0;
                if(res >10 )
                        {
                        token = strtok(gpsbuf,",");
                        if(strcmp(token, gpapb) == 0)
                                {
                                printf( "Token = \"%s\"\n", token );
                                }
                        }//end if(res > 0) 
                }//if (bytes > 0)
        return;
        }// end gps capture
