I cannot understand this bug:

>BOOST_STATIC_ASSERT(sizeof(piece_pos) == sizeof(char) * 8);

sizeof(char) is always 1, so 1*8 = 8
I counted 53bits in piece_pos so its size should be 64/8 = 8
The assert shouldn't trigger...

oh, right. is gcc 4.9 officially released? this looks like a compiler bug, 
especially since it works on all other compilers (clang, gcc 4.8 msvc-12).

Yes gcc 4.9 is officialy released. I get similar errors with 4.8(mingw) too.
r10030
error: http://pastebin.com/Wqa7vxxg

I am going to try a build with MSVC2008 now to see what happens.

you're building a different revision now, right? because I introduced those 
errors last night, and I'm still working on it.

Yes, whatever is included in r10030. I use the snapshot link from the sf.net 
page for libtorrent_aio branch.

However the gcc error are the same regardless.

Forgot to mention that I'll wait for your resolution of course...

Just so you know I now can build libtorrent_aio with gcc 4.9.0 on Windows XP.
The bad news is that as soon as qbt/libtorrent tries to write data to disk I 
immediately get an I/O error with reason "The process cannot access the file 
because it is being used by another process" (roughly translated).
libtorrent trunk/0.16.x works as expected.
