When you say "fails" what kind of failure do you get? Is this a timeout or not? If this is a runtime error, a "seg fault", or whatever but hanging, this is fine with me. > Now, if Fortran2003 allows some recursive access to the same unit (under which > conditions?)

This seems the path to follow to implement a runtime error, isn't it? To be frank, I have a very limited understanding of what you are saying, but I could look again to the code to figure out what it looks like: I understand more or less the technical concepts, but not the actual implementation.
