[PATCH] readelf and DT_RUNPATH

[Thomas Cougnard]

Hi,

When processing the dynamic section and encountering a DT_RUNPATH
entry, the following code (readelf.c:6383)
       case DT_RUNPATH :
         dynamic_info[entry->d_tag] = entry->d_un.d_val;

corrupts version_info, since entry->d_tag is 29 and dynamic_info is

static bfd_vma dynamic_info[DT_JMPREL + 1];
static bfd_vma dynamic_info_DT_GNU_HASH;
static bfd_vma version_info[16];

with DT_JMPREL equals to 23

This patch should fix it.

Thanks
Thomas
