New Problem: llc -O0: Broken module found, compilation aborted!

Hi all,
Here is my problem,

overflow.c:

int main()
{
return 0;
}

$ clang -c -fstack-protector-all overflow.c -emit-llvm overflow.bc
$ llc -O0 overflow.bc

The result seems like the Bug 9259 which had been fixed (r126812). But I find I still have the problem below:

Both operands to a binary operator are not of the same type!
   %aaa = xor i8* %"Call Return Address", i32 1892499360
Instruction does not dominate all uses!
   %aaa = xor i8* %"Call Return Address", i32 1892499360
   call void @llvm.stackprotector(i8* %aaa, i8** %StackGuardSlot)
Logical operators only work with integral types!
   %abbaa = xor i8* %2, %"Call the return address"
Both operands to ICmp instruction are not of the same type!
   %3 = icmp eq i32 1892499360, i8* %abbaa
Instruction does not dominate all uses!
   %3 = icmp eq i32 1892499360, i8* %abbaa
   br i1 %3, label %SP_return, label %CallStackCheckFailBlk
Broken module found, compilation aborted!
0 llc 0x087b2328
Stack dump:
0. Program arguments: llc -O0 overflow.bc
1. Running pass 'Function Pass Manager' on module 'overflow.bc'.
2. Running pass 'Module Verifier' on function '@main'
Aborted

How can I solve this problem?
Thank you

You're generating invalid IR. For development, I'd suggest using a
build with assertions turned on, which will catch this earlier.
