Hi Thuan,
Thanks for reporting this bug. I have checked in a patch to fix it.
There were two problems here. The first was that the target specific
relocation processing code in readelf was not checking for an invalid
symbol index in the relocation. The second was that the code was
maintaining state across multiple invocations, resulting in the use of
a stale pointer.
Cheers
Nick
