Initial attempt to reproduce this error on Linux using
```
export CC=clang
export CXX=clang++
cmake -DCMAKE_BUILD_TYPE=Debug -DARROW_BUILD_TESTS=ON
-DCMAKE_CXX_FLAGS="-Wshadow -Werror" -DARROW_COMPUTE=ON -DARROW_PARQUET=ON ..
make
```
indicates that RE2 has this error also
```
-- stderr output is:

cmake -DCMAKE_BUILD_TYPE=Release -DARROW_BUILD_TESTS=OFF

```
Gives a similar problem with Thrift. The project uses Jira for issue
tracking and can raise this there, though fixes in dependencies may take more
time to get included since the latest versions are not used in the releases.
