Hi,

Why do you believe you need to use a struct in_addr?  Every man page for
gethostbyaddr takes a char * - and the alignment is then I suppose
compiler specific...  You did not indicate a compiler version - is this
gcc or Sun's compiler? 

I do not have access to solaris 2.10 - but what does the manpage on
gethostbyaddr say? What does the prototype in /usr/include/netdb.h indicate?

I suspect that the problem is not in our code - but something in the OS
library.  Is this a known issue with Solaris?

Now scanning the krb5 code - I see one other place in which gethostaddr
is used without a struct (gssapi code) - but it would appear that it is
using malloc - which should be suitably aligned for any variable type...

So - I guess we need to know what is broken - the compiler, the library,
or our code...  Coding a work around without understanding the problem
is probably not best.  Perhaps you can give us more information...
