testcase
Hello,
with the attached testcase, I currently get (-Wall -O1):
a.cc: In member function 'void CGAL::Envelope_divide_and_conquer_2<Traits_,
Diagram_>::_construct_envelope_non_vertical(CGAL::Envelope_divide_and_conquer_2<Traits_,

Diagram_>::Curve_pointer_iterator, CGAL::Envelope_divide_and_conquer_2<Traits_,
Diagram_>::Envelope_diagram_1&) [with Traits_ =

Older g++ didn't have the two mem_ref lines. The closest bug I could find is
PR22238.
