Ah, I see in compiler-rt/test/asan/TestCases/suppressions-function.cpp:

```
// FIXME: atos does not work for inlined functions, yet llvm-symbolizer
// does not always work with debug info on Darwin.
// UNSUPPORTED: darwin
```

So it seems this is a known issue with suppressions in optimized builds.  I'll apply the same thing here unless you have a better idea.
