Adding @NoQ and @xazax.hun , I don't have much experience building CFGs.

================
Comment at: clang/lib/Analysis/CFG.cpp:2855
+
   VarDecl *VD = dyn_cast<VarDecl>(DS->getSingleDecl());

----------------
How about `using`? How about some other shenanigans that obscure the size of the VLA? Can't we just retrieve the size from `VariableArrayType::getSizeExpr` after seeing this `VarDecl`, and add that to the block?
