Instability of Ardour 2.0 solved, 6 weeks of effort pays off! [LWN.net]

A tough bug has been fixed in Ardour, a multi-track audio recording application. See the problem report for details. "Sometimes when you write a complex piece of software like Ardour you are faced with a series of high level, interesting and complex design questions. Unfortunately, its also true that at other times you will be faced with problems that exist at the deepest levels of the software and are often trivial in their extent yet major in their impact. Such has recently been the case with Ardour 2.0, which would not run with any reasonable stability when built with recent versions of the GTK+ GUI toolkit. One Ardour developer (and user), Sampo Savolainen, spent more than 6 weeks debugging this, and just recently got to the bottom of the problem. The error was a single line of code in GTK itself, and manifested in Ardour only because we made a call to a function that was never actually needed."
