Exactly the same issue here! For me it was the nomachine package installed from chaotic-aur that was causing problems.
How did I figure it out? You need to debug execution using gdb:
(note: output is redacted heavily to increase readability)
$ gdb --args host google.com
GNU gdb (GDB) 15.2
Enable debuginfod for this session? (y or [n]) y
(gdb) run
Starting program: /usr/bin/host google.com
free(): invalid pointer

Note the line #36 and #37 making references to /usr/NX/lib/libnxegl.so, which is provided by the Nomachine package. I uninstalled this package (and rebooted to refresh my LD_PRELOAD env variable), and the problem was gone.
