Known problem http://bbs.archlinux.org/viewtopic.php?pid=273807 Not a major issue, more of a PITA. Probably something to do with a foo.supp file.
Please rebuild valgrind and try again. It has a suppression file for glibc-2.6, but it's only built in if 2.6 is detected when it's compiled.
That worked. Thanks
Reopening to fix resolution. No fix was checked in for this report because valgrind is supposed to work like this, so I mark it RESOLVED/INVALID to reflect this.
