Re: Issue where return doesn't really return to octave prompt

[jswensen]

I'm positive the string_value returns OK.  I added the following just 
to verify.

Modified Code
------------------------------------
string propName = args(1).string_value();
cout << "Returned from string_value()" << endl;

// Fails here - never returns to the octave prompt
return octave_value(propName);

Octave Output
-----------------------------------
octave:1> hget(0,'DiaryFile')
Creating root object
After root init
Returned from string_value()


I suppose I could attach with the debugger and figure out where it is getting
stuck.  The problem is I don't think I built Octave with debugging symbols
included.
