[Libtorrent-devel] rTorrent crashing after 10 seconds or so.

[Kalle Alm]

Hi there,

rTorrent seems dead set on crashing on my machine.

I've tried:
    libsigc++-2.0.0
    libsigc++-2.0.17

    SVN version of rTorrent / libtorrent
    rTorrent 0.5.3 / libtorrent 0.9.3
    rTorrent 0.5.2 / libtorrent 0.9.2
    packaged (debian sarge unstable) rTorrent 0.5.1 / libtorrent 0.9.1

I've compiled with:
    gcc-4.0 (yeah, saw the ml archives after and switched)
    gcc-3.4

Next I'm going to compile with gcc-3.3 and see if that does it, however 
I saw someone else mention that 3.4 worked for them. I get the exact 
same error they got. A bt from gdb shows:

Any thoughts on what I might be doing wrong?
