question on allocate memory

Thx.
I debugged the code a bit. And Seems the complex.h is used inherently in the gcc compiler on SUN and this is not the bug.

Another potential one is on allocating memory for a struct ALOS_ORB, which contain another struct. Can anyone tell me how to allocate this by malloc ?
What I did is orb = malloc(sizeof(struct ALOS_ORB));
and I've no idea how to contain another one.

struct ALOS_ORB {
int itype;
int nd;
int iy;
int id;
double sec;
double dsec;
struct ORB_XYZ *points;
};

struct ORB_XYZ {
double pt;
double px;
double py;
double pz;
double vx;
double vy;
double vz;
};
