<pre>
    Fuchsia's clang CI has found a test failure in symbolize_stack.cpp for AArch64. 

Due to another failure, we're not exactly sure when this first appeared, but the failing bot can be found here:  https://luci-milo.appspot.com/ui/p/fuchsia/builders/toolchain.ci/clang-linux-arm64/b8814202726650721633/overview

For both UBSAN and LSAN, the test fails due to an unexpected warning causing matching to fail

```
==180122==WARNING: Symbolizer buffer too small
```

We saw the failure disappear briefly between 1ecc3d86ae3e and c74753f959fe, but I don't see anything in that blame list, or following blame list (7ff7001ba949 to ac7a9ef0ae3a) that suggests this behavior should be different.
