o Minor bugfixes (coverity builds):
- Avoid Coverity build warnings related to our BUG() macro. By
default, Coverity treats BUG() as the Linux kernel does: an
instant abort(). We need to override that so our BUG() macro
doesn't prevent Coverity from analyzing functions that use it.
Fixes bug 23030; bugfix on 0.2.9.1-alpha.
