Hi Reid,
I know some problems(ms compatibility) when throw inside destructor. I have
not yet look like those problems. I am new for clang. I need sometime to
catch up. -:)
Thank you so much for your code review. I had add new patch to address your
suggestion.
Please take look. Let me know if you need more info.
Thanks.
Jennifer

+ if (ClassDecl != nullptr && ClassDecl->getNumVBases())

Yes, you are right. I can either check here, or check if IsMostDerivedClass is
nullptr return instead assertion inside EmitDtorCompleteObjectHandler.
As you know ForVirutalBase is set also for destructor. But we only need this
for ctor.

Thank you! I changed, see my new diff
