[Boost-users] directory_iterator ++operator never return

Hi,

I'm getting a list of the file in a directory like that:

    fs::directory_iterator end ;
    for( fs::directory_iterator iter(myfilepath) ; iter != end ; ++iter )
    {...}

And at some point in this for loop, the ++operator never return, see
callstack (single-thread build).

I found a related thread here:
http://marc.info/?l=boost-users&m=118835374908173&w=2
I compiled boost in threaded and non-threaded mode and still have the same
pb in both mode...

This bug reproduce with iphone os21 and os3.0, boost 1.38.0 (multi/single
thread).

Anybody?

Thanks,
Frank
