The test run is wrapped with a special TESTRUNNER script that ignores
failing tests (there are several tests failing when built with ASAN) and
also ignores LSAN errors (memory leaks - but still visible in the
output).
The test run only fails if a test reports ASAN errors or if it
crashes (or times out, which is like a crash caused by qtestlib's
watchdog timer).
