AFAIK, there isn't explicit locking on directory iterators, but part of 
them uses a shared_ptr which if multi-threading is turned on, will mutex 
the increasing of the reference count.  Some code that does this is 
inbuilt into the library, some gets inlines in your code, therefore 
differences can occour. Another way around this is to link with the 
filesystem source .cpps directly.  That way they are built with your 
current compiler setttings
