Confirmed on x86-linux, sparc-solaris and ppc-AIX so I've removed the Target.
Also verified that valgrind shows the uninitialised memory reads.
This bug breaks common idioms like:
template typename A, typename B
struct compressed_pair : A {
compressed_pair() : A(), second_() { }
A first() { return *this; }
B second() { return second_; }
private:
B second_;
};

--- Comment #4 from gcc-bugzilla at kayari dot org 2006-12-08 10:36 --- Richard, there's no difference between pod() and p() in this case, both are value-initialisations of a POD class, therefore all non-static data members should be value-initialised. I cited 8.5p5 for good reason :) Sun CC 6.1 and 8 and IBM xlC 6 get this right. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30111

For inherit the constructor of p is called which - surprise - as a POD constructor does nothing. Actually read the standard, it does, see 8.5/7 and 8.5/5 the second part about default initializer. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|INVALID | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30111
