[Buildroot] Valgrind on buildroot

[John OSullivan <john.osullivan@cloudiumsystems.com>]

Hi,

I have been trying to get valgrind working on a buildroot 2013.05 arm board.

valgrind -d -d

fails to run with 

--2993:0:aspacem  Valgrind: FATAL: aspacem assertion failed:

--2993:0:aspacem    segment_is_sane

--2993:0:aspacem    at m_aspacemgr/aspacemgr-linux.c:1477 (add_segment)

--2993:0:aspacem  Exiting now.

 

The issue is with the device node for libc

00008000-00106000 r-xp 00000000 00:00 8773       /bin/busybox

0010e000-0010f000 rw-p 000fe000 00:00 8773       /bin/busybox

0010f000-00111000 rw-p 00000000 00:00 0          [heap]

b6dae000-b6eea000 r-xp 00000000 00:00 8937       /lib/libc-2.13.so

                                ^^^^^

                                 dev & ino are always zero

 

valgrind is not expecting a zero for b6dae000-b6eea000 r-xp 00000000 00:00
8937       /lib/libc-2.13.so

 

The build options I am using are:

 

Filesystem images->cpio the root filesystem (initial RAM Filoesystem)

Filesystem images->ext2/3/4 root filesystem

(0)Size in blocks

(0)Inodes (auto calculation)

(0)Reserved blocks percentage

 

Any ideas on how to change this to non-zero so that Valgrind will read it
correctly, it works fine on rabpberrypi, but my filesystem is on the SD
Card,

Other info that might be useful follows

 

 

 

My /proc/self/maps is as follows:
