Given the following
class B{
virtual constexpr ~B() = 0;
};
class D : B{};Example godbolt: https://godbolt.org/z/91zohzbeT
clang++: /root/llvm-project/clang/lib/Sema/SemaDeclCXX.cpp:13781: void clang::Sema::DefineImplicitDestructor(clang::SourceLocation, clang::CXXDestructorDecl*): Assertion `(Destructor->isDefaulted() && !Destructor->doesThisDeclarationHaveABody() && !Destructor->isDeleted()) && "DefineImplicitDestructor - call it for implicit default dtor"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
