From b3e779c090bd6b3ebbd2e811b71891261ce85a9c Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Sun, 16 Nov 2008 09:53:48 +0100 Subject: tests: change misc/printf-surprise so that it doesn't segfault anymore * tests/misc/printf-surprise: Disable MALLOC_PERTURB_, so that "make check" no longer provokes a segfault from printf(1). Before, that would be detected as a known problem and cause the test to be skipped. Adjust the test so that a segfault once again results in test failure. --- tests/misc/printf-surprise | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) (limited to 'tests/misc/printf-surprise') diff --git a/tests/misc/printf-surprise b/tests/misc/printf-surprise index b24e3bef9..34f68649a 100755 --- a/tests/misc/printf-surprise +++ b/tests/misc/printf-surprise @@ -54,6 +54,10 @@ fail=0 mkfifo fifo || framework_failure +# Disable MALLOC_PERTURB_, to avoid triggering this bug +# http://bugs.debian.org/481543#77 +export MALLOC_PERTURB_=0 + head -c 10 fifo > out & ( ulimit -v 10000; env $prog %20000000f 0 2>err-msg > fifo ) exit=$? @@ -78,9 +82,10 @@ case $n_out:$diagnostic:$exit in 10:n:0) ;; # ok, succeeds w/no diagnostic: FreeBSD 6.1 0:y:1) ;; # ok, glibc-2.8 and newer, when printf(3) fails with ENOMEM - *:139) # segfault; known bug at least in debian unstable's libc6 2.7-11 - echo 1>&2 "$0: bug in snprintf causes low-mem use of printf to segfault" - fail=77;; + # With MALLOC_PERTURB_=0, this no longer happens. + # *:139) # segfault; known bug at least in debian unstable's libc6 2.7-11 + # echo 1>&2 "$0: bug in snprintf causes low-mem use of printf to segfault" + # fail=77;; # 10:y) ;; # Fail: doesn't happen: nobody succeeds with a diagnostic # 0:n) ;; # Fail pre-patch: no output, no diag -- cgit v1.2.3-54-g00ecf
