Subject: dns resolver: reorder sockaddr union to make initialization safe
|
|
|
|
some recent compilers have adopted a dubious interpretation of the C
|
|
specification for union initializers, that when the initialized member
|
|
is smaller than the size of the union, the remaining padding does not
|
|
have to be zero-initialized. in the interests of not depending on any
|
|
particular interpretation, place the larger member first so it's
|
|
initialized and ensures the whole object is zero-filled.
