--- Comment #7 from Chris Lattner <clattner at apple.com>  2009-03-04 12:40:19 ---
The problem here is that __CTOR_END__ has magic semantics that the compiler
doesn't know about, and is marked static.  The proper way to tell the compiler
"don't touch" is to use __attribute__((used)), and doing so fixes the problem. 
Please use something like this:

static func_ptr __attribute__((used)) __CTOR_END__[1]
__attribute__((section(".ctors"), aligned(sizeof(func_ptr)))) = { (func_ptr) 0
};

-Chris
