- Removed what appears to be a debug breakpoint.

- Cleared some GCC and Clang warnings. Mostly static analysis false positives, but one of them generated a pretty massive warning in a release build.
- Use -Wno-unused-result since I doubt we're going to address those unless they actually prove to be a problem (and they only appear in release builds).
