Package: libc6-dev
Version: 2.2.4-6
Severity: normal
When using the warning -Wcast-align with GCC, and causing bits/socket.h to be included,
a warning is caused on ARM platforms:
In file included from /usr/include/netinet/in.h:212,
from /usr/include/netdb.h:28,
from netunix.c:18:
/usr/include/bits/socket.h: In function `__cmsg_nxthdr':
/usr/include/bits/socket.h:271: warning: cast increases required alignment of target type
This probably also occurs on other platforms where pointers for 32-bit values must be
32-bit aligned to be sensible (not x86).
This can probably be worked around with an intervening (void *) cast on line 270.

I also can't reproduce this problem on arm glibc 2.3.1.
There is no reply - and I think this bug is already fixed.
Now I close this bug.
