The following testcase causes assertion in clang trunk:

template <auto v>
struct constant{};

template <auto x>
auto operator *(constant<x>) 
{ return constant<(*x)>{}; }

https://godbolt.org/z/acrEETdxo

Assertion:

clang++: /root/llvm-project/clang/lib/AST/ExprClassification.cpp:72:
Cl clang::Expr::ClassifyImpl(clang::ASTContext&, clang::SourceLocation*) const:
Assertion `isPRValue()' failed.
