I'm still confused. alloc->getNumImplicitArgs(): 1 alloc->getNumArgs(): 1 alloc->getArgExpr(0): nullptr I would expect `alloc->getArgExpr(0)` to return the //implicit// parameter, aka. the size of the placement new. I can not see any other `getXX` function which seems applicable. My best bet was the `getPlacementArgExpr` thus I raised this issue here. How can I access the placement new's allocation size of an `CXXAllocatorCall` if not via `getArgExpr()`?
