Hi, thanks for the report.

I'd like to fix this, but the problem is not obvious.  I've done some
experimentation today and cannot reproduce this crash.  Can you suggest
a way that we can trigger it?

As an alternative, you could run ovs-vswitchd under "valgrind" and
provide the reports that it outputs.  Usually, if you can trigger a
problem under valgrind, the reports make it fairly obvious where the
problem lies.
