Subject: [Bug c++/42000]  New: missing -Wuninitialized warning on a user-defined class ctor
Date: Tue, 10 Nov 2009 23:36:00 -0000	[thread overview]
Message-ID: <bug-42000-1186@http.gcc.gnu.org/bugzilla/> (raw)

gcc misses the access to the uninitialized member S::i in the program below
and fails to issue a warning for it.

I would expect to see a warning not only for the access to the member but
also for the definition of the user-defined constructor that fails to
initialize the data member.

$ cat t.cpp && gcc -Wuninitialized -Wall -Wextra -W -c t.cpp
int main () {
    struct S {
        int i;
        S() { }
    } s;

    return s.i;
}
