When running TEST-22 under ASan, there's a chain of events which causes `stat` to output an extraneous ASan error message, causing following fail: ``` + test -d /tmp/d/1 ++ stat -c %U:%G:%a /tmp/d/1 ==82==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. + test = daemon:daemon:755 .//usr/lib/systemd/tests/testdata/units/testsuite-22.02.sh: line 24: test: =: unary operator expected ``` This is caused by `stat` calling nss which in Arch's configuration calls the nss-systemd module, that pulls in libasan which causes the $LD_PRELOAD error message, since `stat` is an uninstrumented binary. The $LD_PRELOAD variable is explicitly unset for all testsuite-* services since it causes various issues when calling uninstrumented libraries, so setting it globally is not an option. Another option would be to set $LD_PRELOAD for each `stat` call, but that would unnecessarily clutter the test code.
