test_sysconfig_config_vars_no_prefix_cache changes sys.prefix and calls get_config_vars(), which caches the new prefix in module globals. tearDown() restored sysconfig._CONFIG_VARS, but not those globals, so the next get_config_vars() call found the cache stale and replaced _CONFIG_VARS with a new dict.
