A workaround would be to configure with --disable-warnings-as-errors
option. Perhaps gcc 11.3 has become much smarter in its dataflow analysis,
hence the warning. If the warning is legitimate, it needs to be dealt with
properly by making changes to the code or at least silencing the warning
(unfortunately, the code is full of situations where the 'this' pointer is
NULL at times).
