Here is a minimum reproducible example. You can experiment with the various
flags. I agree that the `-march` flag may play a role here. I don't have a
machine like this to experiment with unfortunately.
```
int main() {
return __builtin_popcount(17) == 2 ? 0 : 1;
}
```
If this works on your machine then there is probably more investigation for
us to do on the Arrow side. If it fails then it is a gcc bug in this case.
