Still crashing as of post-17 trunk: https://godbolt.org/z/YW7E68n1Y

clang++: /root/llvm-project/clang/lib/AST/Expr.cpp:3302:
bool clang::Expr::isConstantInitializer(clang::ASTContext&, bool, const clang::Expr**) const:
Assertion `!isValueDependent() && "Expression evaluator can't be called on a dependent expression."' 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.
