             Bug #: 14265
           Summary: Crash on invalid trying to delete a member function
                    declared with a typedef'd function type
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


struct S { typedef int F(); F f = delete; }

Gives:

<stdin>:1:35: error: '= delete' is a function definition and must occur in a
standalone declaration
struct S { typedef int F(); F f = delete; }
                                  ^
clang-3.2: include/llvm/Support/Casting.h:79: static bool
llvm::isa_impl_cl<clang::IntegerLiteral, clang::Expr *>:
:doit(const From *) [To = clang::IntegerLiteral, From = clang::Expr *]:
Assertion `Val && "isa<> used on a null pointer"' failed.
[...]
11 clang-3.2       0x00000000021ddd92
clang::Sema::AddInitializerToDecl(clang::Decl*, clang::Expr*, bool, bool) + 130
12 clang-3.2       0x0000000001c75220
clang::Parser::ParseCXXClassMemberDeclaration(clang::AccessSpecifier,
clang::AttributeList*, clang::Parser::ParsedTemplateInfo const&,
clang::ParsingDeclRAIIObject*) + 6704

That diagnostic isn't great, and we shouldn't crash here!
