Hi Beman.

In the meantime I have found the documentation you have mentioned and it lead to my work-around I have already mentioned.

Nevertheless the documentation just states that something was changed but not that I have to adapt existing code.

These "unexpected" exceptions in the operator++ are correct ("no such file or directory") but they were not thrown before boost version 1.56.
So I have made a work-around using the increment(error_code) method, just ignoring the resulting error code.

By the way, these "new" exceptions in the operator++ have only occurred under Linux (gcc 4.8.2) but not under Windows (vc++ 12.0).

Regards,

Armin

See
http://www.boost.org/doc/libs/1_57_0/libs/filesystem/doc/release_history.html

1.56.0 included reorganization and fixes for recursive_directory_iterator::increment.

When you say you are getting "unexpected exceptions", do you mean exceptions you didn't expect that are correctly reporting actual errors or exceptions you didn't expect that are incorrectly reporting errors even though no error actually occurred?

Thanks,
