Hi,
I'm having a "segmentation fault" problem when using ping6.
When testing on ARM9 platforms (i.MX25 and i.MX27), it returns the error:
root at freescale ~$ ping6 ::1
PING ::1 (::1): 56 data bytes
Segmentation fault
When testing on ARM11 and ARM Cortex A8 platforms (i.MX31 and i.MX51),
it works:
root at freescale ~$ ping6 ::1
PING ::1 (::1): 56 data bytes
64 bytes from ::1: seq=0 ttl=64 time=0.331 ms
64 bytes from ::1: seq=1 ttl=64 time=0.214 ms
64 bytes from ::1: seq=2 ttl=64 time=0.176 ms
64 bytes from ::1: seq=3 ttl=64 time=0.155 ms
On all cases, I'm using Linux Kernel 2.6.35 (from Mainline) and Busybox
1.15.0
Does anybody have any idea?
Thanks in advance,
Rogerio Pimentel

This seems to be a Busybox related issue. I'd suggests you to try the latest
version of Busybox (1.17.2), and if the problem persists, ask at the Busybox
mailing list. Don't forget to add strace output to your message.

Do you have something displayed on console ? ( dmesg output )
gdb could tell you where segmentation takes place.

Random guess is that you may be using a userland tuned for ARMv6 or later
but trying to run that on <ARMv6 machines.
You can enable this to see what's going wrong:
config DEBUG_USER
bool "Verbose user fault messages"
help
When a user program crashes due to an exception, the kernel can
print a brief message explaining what the problem was. This is
sometimes helpful for debugging but serves no purpose on a
production system. Most people should say N here.
In addition, you need to pass user_debug=N on the kernel command
line to enable this feature. N consists of the sum of:
1 - undefined instruction events
2 - system calls
4 - invalid data aborts
8 - SIGSEGV faults
16 - SIGBUS faults
