I have been doing "make universe" for the first time in a long time and
I ran into an interesting one.
I had code that looked like:
struct sockaddr_in *sin;
struct addrinfo *res;
- did a getaddrinfo() and then after this I had:
...
sin = (struct sockaddr_in *)res->ai_addr;
For mips, it complained that the alignment requirement for "struct sockaddr_in"
is different than "struct sockaddr" related to the type cast.
I've worked around this by:
struct sockaddr_in sin;
...
memcpy(&sin, res->ai_addr, sizeof(sin));
Is this a real problem or a compiler quirk?
If it is real, it seems to me it would be nice if the alignment requirement for
"struct sockaddr" was the same as "struct sockaddr_in" and "struct
sockaddr_in6".
Is there a "trick" that could be applied to "struct sockaddr" to force good
alignment?
