           Summary: clang crashes for objc method using a bitwise-struct
                    with enum
           Product: clang
           Version: 2.8
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

The following Objective-C program crashes clang 2.8:

typedef enum { A1, A2 } A;
typedef struct { A a : 1; } B;
@interface Obj { B *b; } @end
@implementation Obj @end

Crash happens at clang::ASTContext::getObjCEncodingForTypeImpl(clang:QualType,
std::string&, bool, bool, clang::FieldDecl const *, bool, bool).

Defining an objective-c message that takes in a (B *) parameter or returns (B
*) produces the same error.
