--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Please try to provide meaningful bug titles, and reduce the code to remove
everything that isn't relevant.
This bug reduces from a 72kB testcase to simply:
struct s2 { ~s2() {} };
class s3 : virtual protected s2 { };
class s4 : private s3 { };
class s11 : s4 { } a11;
C++ and EDG accept this, but Clang prints:
test.cc:4:7: error: inherited virtual base class 's2' has private destructor
class s11 : s4 { } a11;
^
test.cc:4:20: note: in implicit default constructor for 's11' first required
here
class s11 : s4 { } a11;
^
test.cc:3:12: note: constrained by private inheritance here
class s4 : private s3 { };
^~~~~~~~~~
