Building dev-libs/boost on an llvm system produces an ICE from the compiler. Reproducible: Always Steps to Reproduce: 1.Try to build boost with clang-17.0.0_rc2 Actual Results: ICE Expected Results: It builds fine clang++: /usr/lib/llvm/17/include/llvm/Support/Casting.h:578: decltype(auto) llvm::cast(From *) [To = clang::CXXConstructExpr, From = clang::Expr]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.

The assertion is only hit when debug use flag is enabled in clang.
there seems to be some kind of progress in one of the linked pullrequests (39319), you might want to revisit and test for backportability of the fix.
(In reply to tt_1 from comment #7) > there seems to be some kind of progress in one of the linked pullrequests > (39319), you might want to revisit and test for backportability of the fix. I don't really consider USE=debug a priority and I don't see it as worthwhile unless it's trivial to backport, and even then... Does this really matter that much to you? If so, why?
