Microsoft Private symbols leaked - whoops

According to Koby Kahane, somebody made an whooopsie @ Microsoft as private debugging symbols were included in the VS 2010 Beta. :)

What are private debugging symbols ?

Public debugging symbols are stripped versions of the original private symbols generated by the build process. They do not contain parameter information and do not contain the names of local variables in functions.
