I've been experiencing several exceptions on OSX, using commit 96f64ac0. Sofar I've tracked down one of them:
A (basic_string) exception occurs when saving a document with a sufficient long filename (more than about 18 characters without the extension). Take any .lyx file and add characters to the name. Then open and save it. As far as I can see this has been introduced with commit bb34445, which contains many changes, including some of the filetools.
