--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---

A straightforward generalisation of this bug report would
be for gcc to warn on code like this:

struct S
{
        int a, b, c;
        S();
};

S::S() : a( 0), c( 2)
{
};

cppcheck finds the problem but gcc and clang don't.

mar19g.cc:11:4: warning: Member variable 'S::b' is not initialized in the
constructor. [uninitMemberVar]

Interestingly, there are about 125 cases of this in the gcc source code,
so this warning would be of immediate use for gcc itself.
