Package: coreutils
Version: 5.2.1-2
Severity: normal


If $LANG is set and VM is low (in this case artificially), "sort"
produces output that will fail the check made by "sort -c".

If available VM is increased or LANG is unset, the problem does not
occur.  Looking at the strace output for successful invocations (where
VM was plentiful) and the failure case, I notice that the issue relates
to a failing mmap() call:-


 open("/usr/lib/locale/locale-archive", O_RDONLY|O_LARGEFILE) = 3
  fstat64(3, {st_mode=S_IFREG|0644, st_size=1814064, ...}) = 0
   mmap2(NULL, 1814064, PROT_READ, MAP_PRIVATE, 3, 0) = -1 ENOMEM
   (Cannot allocate memory)

Locale information is as per below.  I have also reported this at 
https://savannah.gnu.org/bugs/index.php?func=detailitem&item_id=11004,
but since this might actually be a glibc issue, I have reported it here
also.

  Allright, I tested it on a 2.5, removing
/usr/lib/locale/locale-archive (which has roughly the same effect than a
failed mmap) and now setlocale returns NULL properly (hence failing
loudly like it should always have).

  Closing the bug.
