Confirmed.  Reduced testcase:
struct iterator{};
struct ByteIterator : iterator
{
        ByteIterator (){}
        int a[1024];
};
inline ByteIterator f ()
{
        return  ByteIterator ();
}
class ConfLexerCore

        ByteIterator m_matchStart;

ConfLexerCore::ConfLexerCore ()
: m_matchStart (f ())
{ }
