            Bug ID: 94907
           Summary: ICE: Segmentation fault (in check_return_expr)
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: asolokha at gmx dot com
  Target Milestone: ---

gcc-10.1.0-RC20200430 ICEs when compiling the following testcase, extracted
from test/CXX/class/class.compare/class.compare.default/p4.cpp from the clang
10.0.0 test suite, w/ -std=c++2a:

namespace std {
  struct strong_ordering {
  };
}

struct E;

struct D {
  virtual std::strong_ordering operator<=>(const struct E&) const = 0;
};
struct E : D {
  std::strong_ordering operator<=>(const E&) const override = default;
};

% g++-10.1.0 -std=c++2a -c wwmk0dwc.cpp
wwmk0dwc.cpp: In member function 'virtual constexpr std::strong_ordering
E::operator<=>(const E&) const':
wwmk0dwc.cpp:12:24: internal compiler error: Segmentation fault
   12 |   std::strong_ordering operator<=>(const E&) const override = default;
