I saw various sanitizer errors when running check-qtest-ppc64. While
I could just turn off sanitizers, I decided to tackle them this time.
Unfortunately, GLib versions older than 2.81.0 do not free test data in
some cases so some sanitizer errors remain. All sanitizer errors will be
gone with this patch series combined with the following change for GLib:
