Bugzilla Bug 103898

Current valgrind is by default compiled with --enable-pie. On amd64 if I run 
it, it enters an endless loop hogging the cpu (I can see the cpu is 100% in 
kernel mode). My kernel allow me to continue to use my computer but the only 
way to kill valgrind is to reboot. 

Reproducible: Always
Steps to Reproduce:
1.emerge valgrind 
2.valgrind 
 
Actual Results:  
endless loop hogging the cpu in kernel mode 

Expected Results:  
It should at least output: 
valgrind: no program specified 
valgrind: Use --help for more information. 
 

If I recompile it by hand without --enable-pie all works weel (excepts I 
cannot address more than 2Gb as they stated on valgrind website)

Is this the same thing as https://bugs.gentoo.org/show_bug.cgi?id=103898 and
its
corresponding upstream bug report http://bugs.kde.org/show_bug.cgi?id=109861 ?

Does the problem disappear when built without PIE?

Well, this is bug 103898 :-D

Yes I think.

Yes it disappear and all works well 

Alright. The next valgrind version is supposed to be released in a few days.
I will address this problem then.

Oh man! I only just realised that the link I pasted was to this bug. =]

What I meant was... is it the same as this one:
http://bugs.gentoo.org/show_bug.cgi?id=102157

Should be fixed in 3.0.1, because it doesn't build with PIE anymore.

Yes, you are right. This is a duplicate bug. Sorry for that :-)
