<pre>
    A ToT "asserts" build of Clang in the following test case that uses the anonymous struct construct.  I attached the test case per the "HowToSubmitABug" instructions:
[anon-6e7926.cpp.txt](https://github.com/llvm/llvm-project/files/14780063/anon-6e7926.cpp.txt)
[anon-6e7926.sh.txt](https://github.com/llvm/llvm-project/files/14780067/anon-6e7926.sh.txt)

The assertion message is:
clang++: /tmp/dgilmore/tt/clang/lib/CodeGen/CGExprAgg.cpp:1751: void {anonymous}::AggExprEmitter::VisitCXXParenListOrInitListExpr(clang::Expr*, llvm::ArrayRef<clang::Expr*>, clang::FieldDecl*, clang::Expr*): Assertion `(Field->isUnnamedBitfield() || Field->isAnonymousStructOrUnion()) && "Only unnamed bitfields or ananymous class allowed"' failed.
