I'm not entirely sure I've got all the locations where it needs to be replaced with getVtblStruct.

I'm not entirely sure I've got all the locations where it needs to be replaced with getVtblStruct.

Looks to me like all have been replaced. Could you put a comment to explain the functiongetVtblStruct ?Maybe give a tiny llvm bc code fragment example with and without ASan. I will merge it after your comments.

It should be ready. Let me know if it needs any further update.
