Is it known/expected that Swift will not build with Clang 3.9.0? My personal build-bot recently updated its upstream dependency from Clang 3.8.1 to Clang 3.9.0 and since then it will not build the swift-3.0.1-RELEASE. It seems that others have noticed this (https://gist.github.com/eyeplum/94627aac7b4fa609108fd24b960a8805) but I don't know if it has been reported or not.
The actual build error looks like this: swift: /build/swiftc/src/llvm/include/llvm/Support/Casting.h:95: static bool llvm::isa_impl_cl<swift::InOutExpr, const swift::Expr *>::doit(const From *) [To = swift::InOutExpr, From = const swift::Expr *]: Assertion `Val && "isa<> used on a null pointer"' failed. 0 swift 0x0000000003316df5 llvm::sys::PrintStackTrace(llvm::raw_ostream&) + 37 1 swift 0x00000000033152f6 llvm::sys::RunSignalHandlers() + 54 2 swift 0x00000000033174ba 3 libpthread.so.0 0x00007f8fd532d080 4 libc.so.6 0x00007f8fd3a4204f gsignal + 207 5 libc.so.6 0x00007f8fd3a4347a abort + 362 6 libc.so.6 0x00007f8fd3a3aea7 7 libc.so.6 0x00007f8fd3a3af52 8 swift 0x0000000000ffea91 9 swift 0x0000000001093a5b 10 swift 0x0000000001091d22 11 swift 0x0000000001093bb0 12 swift 0x0000000001091d4c 13 swift 0x0000000001093a6f 14 swift 0x0000000001091d22 15 swift 0x000000000109239e 16 swift 0x00000000010911de swift::Expr::walk(swift::ASTWalker&) + 46 17 swift 0x0000000000ff5588 swift::performSyntacticExprDiagnostics(swift::TypeChecker&, swift::Expr const*, swift::DeclContext const*, bool) + 680 18 swift 0x0000000000ecac4f swift::TypeChecker::typeCheckExpression(swift::Expr*&, swift::DeclContext*, swift::TypeLoc, swift::ContextualTypePurpose, swift::OptionSet<swift::TypeCheckExprFlags, unsigned int>, swift::ExprTypeCheckListener*, swift::constraints::ConstraintSystem*) + 1023 19 swift 0x0000000000f48e1f 20 swift 0x0000000000f47a84 21 swift 0x0000000000f46d85 22 swift 0x0000000000f4602a swift::TypeChecker::typeCheckFunctionBodyUntil(swift::FuncDecl*, swift::SourceLoc) + 330 23 swift 0x0000000000f45e89 swift::TypeChecker::typeCheckAbstractFunctionBodyUntil(swift::AbstractFunctionDecl*, swift::SourceLoc) + 25 24 swift 0x0000000000f46a10 swift::TypeChecker::typeCheckAbstractFunctionBody(swift::AbstractFunctionDecl*) + 176 25 swift 0x0000000000f02a97 26 swift 0x0000000000f035d1 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) + 1249 27 swift 0x0000000000c9032b swift::CompilerInstance::performSema() + 3723 28 swift 0x00000000007df2f8 29 swift 0x00000000007de21c swift::performFrontend(llvm::ArrayRef<char const*>, char const*, void*, swift::FrontendObserver*) + 2572 30 swift 0x00000000007a67af main + 3423 31 libc.so.6 0x00007f8fd3a2f291 __libc_start_main + 241 32 swift 0x00000000007a3cba _start + 42 Stack dump: 0.
