Hi, we're seeing breakages building LLVM for Fuchsia, that appear to be caused by https://reviews.llvm.org/D115919.
for whatever reason the changes to compiler-rt/lib/sanitizer_common/sanitizer_common_interceptors.inc seem to be the culprit, since I'm not sure how changes to the test could cause this.
The error message is as follows:
```
Command Output (stdout):
