Certain values of metadata_to_use reproducibly produce segmentation faults #1321

Bug report

Describe the bug

Some choices of metadata_to_use cause mpd to reproducibly segfault on startup. A minimal combination that I have found to work is:

metadata_to_use         "artist,album,title,track,artistsort,albumartist,title,composersort"

Interestingly, the following does not segfault:

metadata_to_use         "artist,album,title,track,artistsort,albumartist,composersort"

but instead gives exception: error parsing metadata item "(null)".

Here is my configuration file:

music_directory         "/var/lib/mpd/music"
playlist_directory              "/var/lib/mpd/playlists"
db_file                 "/var/lib/mpd/tag_cache"
pid_file                        "/run/mpd/pid"
state_file                      "/var/lib/mpd/state"
sticker_file                   "/var/lib/mpd/sticker.sql"

user                            "mpd"
metadata_to_use         "artist,album,title,track,artistsort,albumartist,title,composersort"
