            Bug ID: 95719
           Summary: SEGV in tree_check
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED

  Target Milestone: ---

With a locally-built recent GCC 11 trunk (git rev
48b6386f5d0bdcbe5c901678a043516d544a9f7f), but not with e.g.
gcc-c++-10.1.1-1.fc32.x86_64:

> $ cat test.cc
> struct S1 { virtual ~S1(); };
> struct S2 {
>     virtual ~S2();
>     virtual void f();

> struct S3 final: S1, S2 { using S2::f; };
> void g(S3 & s) { s.f(); }

> $ g++ -fsyntax-only test.cc
> test.cc: In function ‘void g(S3&)’:
> test.cc:7:22: internal compiler error: Segmentation fault
>     7 | void g(S3 & s) { s.f(); }
