Dear mailing list,
I downloaded the latest stable branch of Couenne by SVN on 21 February
2009. I had no problems compiling on my Gutsy Gibbon Ubuntu machine.
Next, I wrote my model and a script in Ampl and created some data. When
I ran the script, it created several pages of data before crashing,
which ended in the following:
