#7276 closed bug (duplicate)

gettext-tools/configure from gettext- triggers BFS corruption

Reported by: mmadia Owned by: axeld
Priority: normal Milestone: R1
Component: System/Kernel Version: R1/Development
Keywords: Cc:
Blocked By: Blocking:
Platform: All


gettext-'s gettext-tools/configure script can reliably generate BFS issues, through testing "rmdir"

The issue seems to be rmdir <dirname>/./ . Both <dirname>/ and <dirname>/. do not trigger the BFS issues (judging by syslog output).

To reproduce, simply cd gettext- ; ./configure

gettext-tools/configure snippet

(line 38205)

    { $as_echo "$as_me:${as_lineno-$LINENO}: checking whether rmdir works" >&5
$as_echo_n "checking whether rmdir works... " >&6; }
if test "${gl_cv_func_rmdir_works+set}" = set; then :
  $as_echo_n "(cached) " >&6
  mkdir conftest.dir
     touch conftest.file
     if test "$cross_compiling" = yes; then :
  gl_cv_func_rmdir_works="guessing no"
  cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */
#include <stdio.h>
           #include <errno.h>
           #include <unistd.h>

main ()
return !rmdir ("conftest.file/") || errno != ENOTDIR
       || !rmdir ("conftest.dir/./");
  return 0;
if ac_fn_c_try_run "$LINENO"; then :
rm -f core *.core core.conftest.* gmon.out bb.out conftest$ac_exeext \
  conftest.$ac_objext conftest.beam conftest.$ac_ext

     rm -rf conftest.dir conftest.file
