One of the reasons I think it has to do with specific functions, is that we've got one system that runs heavily threaded floating point heavy code (a search engine ranker) and that hasn't had this problem in the past seven days. The database builder is the only piece of software giving us trouble, which happens the only software we have that uses floorf(). So after some testing, I could remove all code but the floorf() and still get the exception, but without it, I'm until now unsuccesful.
