>Organization:
Trolltech AS
>Environment:
FreeBSD reticent.troll.no 6.0-RC1 FreeBSD 6.0-RC1 #28: Mon Oct 17 08:46:08 CEST 2005     root@reticent.troll.no:/usr/obj/usr/src/sys/RETICENT  i386
>Description:
              When using valgrind from ports to debug a program, most calls to malloc(3) generate a warning about a comparison depending on uninitialized values.
>How-To-Repeat:
              Run valgrind on /bin/ls
>Fix:
              Apply the attached patch to src/lib/libc/stdlib/malloc.c, it makes sure that all bits in the pginfo.bits bitfield are initialized.
