I spent just a few minutes in the OpenIndiana code base and found it rife with potential issues. For example, in the hsfs file system, there are no pointer assertions to protect against null pointers:

http://src.illumos.org/source/xref/illumos-gate/usr/src/comm...

lines 158 thru 171... are just one example.

While yes, you could find this anywhere in any code base, we're talking about OpenIndiana. If this kind of issue is present in the file system handler, there's NO way this project is ready for prime time, never mind a production release.
