--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> 2012-10-31 08:26:10 UTC ---
Patch doesn't work and elf_get_dynamic_info is miscompiled:
0xf7dddc88 <+5224>: neg %eax
0xf7dddc8a <+5226>: lea (%rcx,%rax,4),%eax
---Type <return> to continue, or q <return> to quit---
=> 0xf7dddc8d <+5229>: mov %edx,-0x40000300(%rax)
(gdb) p *(int *) $rax
Cannot access memory at address 0x37ffe064
