I haven't actually run the test under GETTEXT_POISON, but I stongly suspect it's the test, or more accurately the helper function 'test_i18ngrep'. The test in question runs test_i18ngrep ! "refusing to lose untracked file at" err which fails in normal test runs, because 'grep' does find the undesired string; that's the known breakage. Under GETTEXT_POISION, however, 'test_i18ngrep' always succeeds because of this condition: if test -n "$GETTEXT_POISON" then # pretend success return 0 fi and then in turn the whole test succeeds.
