Bugzilla Bug 14924

I have tried to compile prelink-20021002-r1.

I got the error:
../src/prelink:
/var/tmp/portage/prelink-20021002-r1/work/prelink/testsuite/reloc1: Could not
find variable copy reloc is against

The exact same error occurs in all of the following tests: reloc{1,3,6,7} and
shuffle{1-5}.

I've noticed this error mentioned once, on a Redhat forum, and it was in
reference to Gentoo users.

I'm using binutils-2.13.90.0.16-r1, gcc-3.2.1-r6, glibc-2.3.1-r2, all compiled
last night.

Reproducible: Always
Steps to Reproduce:
1. 'emerge prelink'
2. less /var/tmp/portage/prelink-*/work/prelink/test/reloc1.log
Actual Results:  
Lots of test failures

Expected Results:  
 

Portage 2.0.46-r9 (default-x86-1.4, gcc-3.2.1, glibc-2.3.1-r2)

Could be a gcc problem related to the bad loop bug on K6 and gcc-3.2.1.  

Upgrade to gcc-3.2.2, and remerge glibc, elfutils and prelink.

And?

I have an almost identical bug. Rebuilding my Gentoo system using 1.4rc3 
from Stage 1 off the CD, using portage 2.0.47-r7, everything built fresh 
since that release. 
 
I'm using gcc 3.2.2 on an Athlon XP ; have also tried reemerging gcc glibc 
and binutils with much lower optimisation ; the alternative prelink ebuilds in 
portage ; removing libelf and adding elfutils. 
 
Still same results on success/fail on prelink. Reloc 1,3,6 and all the 
shuffles fail, Reloc 2,8,9 and the layouts pass.  
 
Same setup worked on a 1.4rc2 Stage 1 build with the same optimisations. 

Further to my previous comment ; 
 
I rebuilt binutils, gcc and glibc with -O2 -arch=i686 (e.g. the default 
make.conf) & it still gave the same errors. 
 
Using the same data (burnt to CDROM, no net access), built a new Gentoo 
system on the same level, prelink built. Changed to -O3 -arch=athlon-xp 
etc etc and rebuilt it, didn't work. Changed it back and it still didn't work.  
The hardware was almost identical KT266 VIA board + RIVATNT2. 
 
A bit stuck now as to what to try next :(

Patch to fix copy reloc problem.

This is a bit of a hack, but it works for me.

I was debugging the prelink utility because I was getting this problem. I
managed to produce a patch that fixed the problem for me. I will send this
patch to the prelink author, so he can produce something better.

This patch will break 64 bit machines, and for what I found, this problem only
seems to happen on 32 bit machines. At least it happens on my pentium3.

Added the patch, I recomend using a newer version of prelik though!
The current stable version is way old!
