Intermittent crash: `Assertion 'is' failed.`

Bug report

Describe the bug

Since updating to v0.22.7 from the Arch repositories, I have been getting periodic crashes due to assertion failures. I have not been able to reproduce a direct cause.

Expected Behavior

No crashes.

Actual Behavior

MPD crashes, after logging:

mpd: ../src/input/LastInputStream.cxx:42: void LastInputStream::OnCloseTimer(): Assertion `is' failed.`
