CWE-407: is_contained(BlockList, Succ) inside nested for loops in
computeOutliningColdRegionsInfo. Fix: SmallPtrSet for O(1) membership.
GCC deep scan: CLEAN (bitmaps/hash_sets throughout).
swift-0001: QualifiedLookupRequest::evaluate (NameLookup.cpp:2860) pushes
protocol superclassDecl onto BFS stack unconditionally — visited.insert()
return not checked. Nearby ClassDecl arm (line 2833) is correctly guarded.

re-traversal on every qualified member lookup. Fix: check .second.
llvm, gcc, webkit: CLEAN in available sparse-clone code.
