llvm dev - Nov 2012 - [LLVMdev] Undefined symbols for architecture i386: "EH_frame0",

linking this IR file: http://pastebin.com/HnUsSshB

with triple i386-apple-ios to an .o file

and linking it using:

ld -arch i386 -ObjC "EmptyProject17.o"  -lSystem -lobjc  -framework 
CoreGraphics -framework Foundation -framework UIKit -dynamic -o 
"i386-EmptyProject17"  -objc_abi_version 2 -no_implicit_dylibs
-lcrt1.o
-syslibroot 
"/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk"
-force_load 
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a"
-demangle -ios_simulator_version_min 5.0

I get this error:
Undefined symbols for architecture i386:
   "EH_frame0", referenced from:
_main in EmptyProject17


what am i missing here?
The asm for this http://pastebin.com/KCSWSDBm doesn't contain EH_frame0 
but i heard it that those are the ".cfi*" opcodes. I don't
understand
why it fails on not finding EH_frame0 because it's defined by this 
object itself.

thanks,

Carlo Kok

This ended up being line 16:
@"\01L_OBJC_PROTO_REF_$_0_IIntf"

if that gets renamed to:
@"\01l_OBJC_PROTO_REF_$_0_IIntf"

It all works fine.
