[CM] loading libc_s7.so

Probably yes. I can reproduce the problem after the change of alsa
settings for pipewire:

# snd 21.5, alsa-lib-1.2.5.1
./configure --without-gui

# no pipewire
./snd

New settings in ~/.asoundrc for pipewire (compiled from git 20210703):

pcm.pipewire { type pipewire }
ctl.pipewire { type pipewire }
pcm.!default pcm.pipewire
ctl.!default pcm.pipewire

# The repl hangs with or without pipewire daemon; the new alsa
# settings seem the problem.
./snd
