There are two "Bad file descriptor" errors for two different file
descriptors at the same time. One is for an alsa fd and the other one
is probably an asyncmsgq fd of the alsa sink. My wild guess is that the
pollfd array that is stored in the alsa sink's pa_rtpoll struct gets
corrupted. That can be hard to debug, if it's some unrelated code that
has a bug that makes it write to a random memory location... If the
problem is reproducible, I would start by logging all changes to the
pollfd array and the final array contents at the time of the crash to
see if the array contents have changed to something unexpected.
