Thanks. That helped.
msync() is failing with an EACCESS errno. That translates to a windows
error: ERROR_LOCK_VIOLATION. According to the ancient wisdom of google,
it is not uncommon for the FlushViewOfFile() function to return with
this error in some cases.
I added a retry to the function fhandler_disk_file::msync and tried
running rtorrent to download a debian iso (which seemed to be what you
were doing). I could duplicate your problem before adding the retry but
I don't see it now.
The command I was using:
rtorrent http://cdimage.debian.org/debian-cd/6.0.6/i386/bt-cd/debian-6.0.6-i386-CD-1.iso.torrent
I'm generating a snapshot now. Please give it a try when it shows up.
And, Corinna, please if the change I made to your function is wrong or
you just don't like my variable names or comments please feel free to
expunge what I did with extreme prejudice.
I can't explain what in the newer snapshots would cause a difference
in behavior other than the fact that they were being built with a
newer compiler and a revamped configure script.
