I have just upgraded my Mac to Lion and code that worked fine under
snow leopard is giving me a run-time exception when constructing a
directory_iterator.

The error I am getting is "malloc: pointer being freed was not allocated"

The line in question that raises this error is:
        for ( directory_iterator itr( my_path ); itr != end_itr; ++itr )
taken directly from the example and working fine under windows.

This is version 1.49 installed with MacPorts.

Is this a known problem? I found some vague references to a similar
problem in an earlier version of boost but no solution.

I have confirmed that I only have 1 copy of the headers and libs on
the system and in the correct path. The date stamp on the files
matches the last time I did a macports update so this should be the
matching library for the header.
Please note that I am a real novice to Mac development and have only
just started porting code from windows for less than a month.

Thanks in advance,
Martin
