mocp -a may abort due to unexpected events if playback is active

[dreamlayers]

Adding a multiple folders with one album in each via mocp -a on a cifs filesystem mount in Ubuntu 24.04 sometimes aborts at:

mocp/interface.c

Lines 1248 to 1249 in 48b48e5

	else if (no_iface)
	abort (); /* can't handle other events without the interface */

In the gdb backtrace, selecting this stack frame and doing info locals shows type = 2:

mocp/protocol.h

Line 48 in 48b48e5

#define EV_CTIME 0x02 /* current time of the song has changed */

I guess the issue happens when such other events happen while that function is executing. If the function takes a longer time to run because many files are being added and/or the filesystem they're on is slow, this increases chances of this happening.

First stopping playback via mocp -s seems to prevent this problem. When I was setting a new playlist via mocp -sc followed by mocp -ap I didn't get any aborts.

Maybe this should be posted at the bug report forum at https://moc.daper.net/forum/19 but I don't see how to register on the forums over there.

BTW. I use MOC almost exclusively on NFS (over LAN) and never had similar problem, interesting.
