I had the same problem. I found a bug in radar_grid.c. I sent the following patch into Unidata July 15 - give it a try:

ystart = (int)YB; ystop = (int)YT;
/*printf("look xstart %d xstop %d ystart %d ystop %d\n",xstart,xstop,ystart,ystop);*/ 

! if(((xstop - xstart)*(ystop - ystart)) > xcsiz)
   {
!    xcsiz = (xstop - xstart)*(ystop - ystart);
printf("increasing MAXNEX to %d [%d %d %d %d]\n",xcsiz,xstop,xstart,ystop,ystart); 
   xin = (float *)realloc(xin, xcsiz*sizeof(float));
   xout = (float *)realloc(xout, xcsiz*sizeof(float));

   xin = (float *)realloc(xin, xcsiz*sizeof(float));
   xout = (float *)realloc(xout, xcsiz*sizeof(float));
