Package: transmission-daemon Version: 3.00-1 Severity: normal X-Debbugs-Cc: t...@debian.org
Today I noticed transmission-daemon being down after a reboot, and saw it is crashing with a malloc error. After some debugging, I found out that this only happens if I am using the `--portmap` option *and* a local minissdpd is running. $ /usr/bin/transmission-daemon -f --log-debug --portmap malloc(): invalid next size (unsorted) Aborted A GDB backtrace does not show anything interesting: Starting program: /usr/bin/transmission-daemon -f --log-debug --portmap [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".
