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
