Hello Juan,
I am experiencing the same problems that were reported in the closed bug
report http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=397513, except that
i am experiencing it with a different group of programs which are also from
coreutils, namely su, tar, ping6, stty.
I am following Jim Meyering's instructions to run with a different locale
env LC_ALL=C /bin/su
but I still have the same segfault

The common theme to all of these seg faults seems to be that it is freeing
(via munmap) memory that hasn't been allocated. But I am unsure how to
further diagnose this problem.
