The tests posix/bug-ga2-mem and resolv/mtrace-tst-leaks2 are failing on fedora 33 as mtrace reports memory leaks. The /etc/nsswitch.conf differs between Fedora 32: hosts: files dns myhostname Fedora 33: hosts: files resolve [!UNAVAIL=return] myhostname dns Therefore /lib64/libnss_resolve.so.2 (from systemd) and the dependencies libgcc_s.so.1 and libpthread.so.0 are loaded. Usually all malloc'ed resources from getaddrinfo / gethostbyname are freed and the libraries are dlclose'd in nss/nsswitch.c:libc_freeres_fn (free_mem). Unfortunately, /lib64/libnss_resolve.so.2 is marked with DF_1_NODELETE. As this library is not unmapped, you'll see "Memory not freed". Therefore those tests are now only relying on libnss_files.so by making them test-container tests and providing the required configuration files. By moving the tests to tests-container, those are now running with "make check". Therefore the mtrace part of the tests are also moved from "make xcheck" to "make check". bug-ga2.c is now using test-driver.c in order to support WAIT_FOR_DEBUGGER environment variable.
