Description John Reiser 2004-11-30 23:42:38 EST

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)

Description of problem:
The test program posix/tst-fnmatch uses an uninitialized variable for
test 307 in posix/tst-fnmatch.input:
C               "\\"                    "[\\\\-a]"             0
and the error lies in internal_fnmatch (in /lib/tls/libc-2.3.3.so).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. valgrind --tool=memcheck tst-fnmatch <bug.input
C               "\\"                    "[\\\\-a]"             0

Actual Results:  ==1974== Memcheck, a memory error detector for x86-linux.
==1974== Copyright (C) 2002-2004, and GNU GPL'd, by Julian Seward et al.
==1974== Using valgrind-2.2.0, a program supervision framework for
==1974== Copyright (C) 2000-2004, and GNU GPL'd, by Julian Seward et al.
==1974== For more details, rerun with: -v
==1974== Conditional jump or move depends on uninitialised value(s)
==1974==    at 0xB84B1A: internal_fnmatch (in /lib/tls/libc-2.3.3.so)
==1974==    by 0xB87E8F: fnmatch@@GLIBC_2.2.3 (in /lib/tls/libc-2.3.3.so)
==1974==    by 0x8048F8D: main (tst-fnmatch.c:129)
  1: fnmatch ("[\\\\-a]", "\\", 0) = 0
  1 tests,   0 failed

Expected Results:  No complaint from memcheck.

That change is in glibc-2.3.3-86 and above.
