hang when doing a fastdebug build (original) (raw)

There is something about a patch I am working on that results in a hang when exiting an app with a fastdebug build but not with a product build. The results of ctrl+break follow. Could someone look at this and give me a hint as to what the deadlock is? Thanks, Pete
