[Bug c++/36814] New: G++ won't warn about an uninitialized value

["jellegeerts at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hello,

I've compiled the code below using `g++ -Wuninitialized -O test.cc -o test':

<<<<<<<<<<<<<<<
bool cMyClass::Init()
{
    bool retval;

    if (some_function())
    {
        // If the `goto' is executed, 'return retval;' will use the
        // uninitialized value of 'retval'.
        goto error;
    }

    retval = true;
error:
    return retval;
}
>>>>>>>>>>>>>>>

The problem is explained in the code comments above.

I think that GCC is supposed to warn about this, is that correct?

Thanks, Jelle
