Hi @MaskRay 

If compiling with ASAN, this starts failing with this patch:
```build-all-asan/tools/clang/unittests/AllClangUnitTests --gtest_filter=PPMemoryAllocationsTest.PPMacroDefinesAllocations```

It fails with:
```
Note: Google Test filter = PPMemoryAllocationsTest.PPMacroDefinesAllocations

It still fails on latest trunk (030e141fa93).
