Package: rtorrent
Version: 0.8.9-2
Followup-For: Bug #599913
rtorrent 0.8.6-1 used to be crashing every several weeks for
me. (Though I do not actually remember whether there were
std::bad_alloc messages. I thought so but several recent crashes in
squeeze had basic_string::resize messages.)
After upgrading to wheezy rtorrent started to crash much more
often. Either immediately after start or about half an hour later,
often with the messed up *** glibc detected *** rtorrent: corrupted
double-linked list: 0x094c7a18 *** messages, requiring reset in the
terminal to get readable output from any subsequent command.
Running rtorrent under valgrind appears to prevent crashes.
After recompiling libtorrent 0.12.9-3 with DEB_BUILD_OPTIONS=nostrip
I get the following:
