Hi, I was trying to put into https://cppinsights.io/ the header of this header-only library - zpp_bits. However, cppinsights crashed with the following message:

insights: /usr/lib/llvm-15/include/clang/AST/ExprConcepts.h:451: clang::Expr* clang::concepts::NestedRequirement::getConstraintExpr() const: Assertion `!isSubstitutionFailure() && "getConstraintExpr() may not be called " "on nested requirements with " "substitution failures."' failed.
Stack dump without symbol names (ensure you have llvm-symbolizer in your PATH or set the environment var `LLVM_SYMBOLIZER_PATH` to point to it):
