Extended Description

Printing the AST of the following Objective-C program crashes clang 3.3 (Apple Xcode 5) and my local version of clang 3.4 (see stack trace with symbols).

The issue transposes to a crash of the AST dumper when the problematic expression "A.foo.x" is moved into a typeof().

Not sure if the bug is about the printer or the parser. (The AST looks weird to me in first place.)

cat >test.m << EOF
struct S { int x; };

@​interface A

• (struct S)foo;
  @​end

void f() {
int _y = A.foo.x;
}
EOF

clang -Xclang -ast-print -c test.m
