Why does code work on Solaris but not on Linux?

I have a C code which is working fine on Solaris machine but the same code is giving segmentation fault for sometimes and some other time producing different output.

The following is the part where I am getting difference in both the machines:

FILE *inf;
unsigned char *ptr;
unsigned short *ds;
int n, s; 
char work[100];

inf = (FILE *) fopen("Filename", "r");  
s = fseek(inf, 0, SEEK_SET);
n = fread(work, 1, sizeof(work), inf);
ptr = (unsigned char *)work;
ptr += 8;

count = 0;
ds = (unsigned short *) ptr;
count = *ds;

When I am printing the value of count it is 15 in Solaris Machine and 768 in Linux machine.

Please suggest me the changes to be done in code on Linux machine.

I don't think it's (just) the endianness. 15 = 0x000F. 768 = 0x0300. It might be related to the size of char though. Try printing CHAR_BIT on both machines and see what you get.
