heya somebody

i wrote this procedure, but when i put a call for it in main(), compile
and run,
the program doesn't even finish the self-setting-up phase.
i use rhide, with -O3 tag.
here's the proc: (it's supposed to read a chain of int coords from file
fn, into
the chain based at blp).

typedef struct landp //points read from file
{
 int relx,y;
 landp * r; //right
};

void readland(char * fn,landp ** blp) //blp=baselandp
{
 landp * lp;
 *blp=NULL;
 FILE * f=fopen(fn,"rb");
 if (f)
   {
    int read;
    fread(&read,2,1,f);
    while (read!=0xffff)
      {
       if (*blp) lp=(lp->r=(landp *)malloc(sizeof(landp)));
       else *blp=lp=(landp *)malloc(sizeof(landp));
       lp->relx=read;
       fread(&read,2,1,f); //not sure how to do it with direct pointer
access
       lp->y=read;
       fread(&read,2,1,f); //not sure how to do it with direct pointer
access
      }
    lp->r=NULL;
    fclose(f);
   }
}

i can't see any reason for this to happen... :-(
can you please tell me why?
                                                  Avishay
