Thanks for your help! I will work on testing in calendar week 21.



================
Comment at: llvm/lib/CodeGen/WinEHPrepare.cpp:966
 
-        if (FuncletBundleOperand == FuncletPad)
+        if (!FuncletPad || FuncletBundleOperand == FuncletPad)
           continue;

Yes, apparently it is necessary. There are cases, where `CodeGenFunction::getBundlesForFunclet()` registers a "funclet" bundle operand, but the `FuncletPad` here is null. My guess was it might be due to optimizations?
