FWIW, the issue seems to be that the virtual table for the static NetworkTableMode::Server object (an instance of NetworkTableServerMode class) is not yet initialized when NetworkTables::Initialize() is invoked; when NetworkTables::Initialize() attempts to use the NetworkTableServerMode object to invoke the virtual member function CreateNode(), the virtual table for the Server object hasn't yet been initialized because the NetworkTableServerMode constructor hasn't yet been invoked. So as Greg said, it's unordered static object construction that's causing it. However, it's happening within the WPILibrary itself (from within the RobotBase constructor), rather than in our robot code.
Final Update: Looks like I goofed.

I believe this was happening because I was using a project created with last year's Sample Project creator in WindRiver, even though I'd updated to the latest 2014 release of the FRC C++ Update.

When I recreated the project (same process, but it was created after the 2014 update was installed into windriver), I'm not seeing this issue.

My apologies if I've wasted anyone's energy or time.
