Bug#857625: munmap_chunk(): invalid pointer happened to me too

Sat, 08 Sep 2018 04:00:23 -0700 

I think I've hit the same bug.
Pan 0.145, Debian unstable/amd64:

$ pan --debug

/home/yavor/.pan2/article-cache
(queue.cc:292:process_task) in process_task with a task of type SAVE
(task-article.cc:355:use_decoder) decoder thread was free, enqueued work

I was reading gmane.linux.debian.devel.changes.unstable when Pan
started going offline with a message that there was no space left on
the device (which is not true).

I attach the tasks.nzb file.  Removing it fixes the problem but it is
obvious that's a bug.
