Hi Thomas,

Thanks for your note.

I don't see anything wrong with the code, but it is possible that I'm 
missing something.  This code has been in Ipopt for a number of years now 
and used on several platforms with many different compilers, and never 
lead to a problem.  If you find out why an error is reported and how that 
can be fixed, please let us know (preferrably as a ticket on the Ipopt 
Trac page).

Thanks

Andreas
