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:
r...@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:
r...@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
