Hi Zhouxuan,

I noticed that, too. It comes from my patch for EH handling. 
Something has changed in LLVM and I did not correct the patch 
yet. (I correct it as soon as I understand the LLVM changes 
causing the failure.)

It works if you do not apply the patch. But then you get no 
exception handling...
