The included file compiles and links fine with both GCC 1.42 and 2.2.2.
on a SS2 running 4.1.1.

However, when run, I get a Bus Error in inet_netof() in the executable
compiled with 1.42, while the 2.2.2 version runs and works fine. GDB
claims that the input struct 'myip' is identical in both cases. I've
checked the include files used by both and they look OK (I've even
tried using the 2.2.2 "fixed" includes with the 1.42 compiler). I
haven't yet looked at the assembled output, but I have no experience
with SPARC code, so that would probably prove fruitless. 

You may say, "So? Use the 2.2.2 version." I would, except that nifty
tool Purify doesn't work with 2.x objects, only 1.x objects, and I
*really* want to "purify" the application that contains this fragment.

What's up here?


#include <stdio.h>
#include <malloc.h>

#include <sys/types.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>

main(int ac, char **av)
{
    struct hostent *he;
    struct in_addr myip;
    unsigned int netp;
	
    he = gethostbyname(av[1]);	/* name of this host expected as 1st parm */

	memset(&myip,'\0',sizeof(struct in_addr));
    memcpy(&myip.s_addr, he->h_addr_list[0], sizeof(myip.s_addr));
    netp = inet_netof(myip);	/* kaboom */
}
