Bus Error (SIGBUS) when scanning .wv and .mpc files on arm (raspian) about mpd

[MaxKellermann]

As you already noticed, your backtrace is useless without debug symbols, so please write a new bug report as soon as you are able to provide useful information.

I comnpiled Music Player Daemon 0.24 (v0.23.12-745-gc69b9780d) and the problem doesn't occur with that.

[molecular]

just for completeness:

• issue occurs on 0.22.11
• issue does not occur on v0.23.13

backtrace (differnt file, an mp3, just assuming it's same issue, to do with ape tags):
