Thanks for putting all the patches in a single attachement, it was
much easier like that. (there was no patch 4.  Is it not needed
anymore?)

I'm still getting the bug.
I have HEAD from Feb 12th.
 + the Precord patches you sent.
 + fix-reverse-plt-error.txt
 + stopped.diff from Volodya (although it is not needed for this test)

I compile with
g++ (GCC) 4.1.2 20070115 (prerelease) (SUSE Linux)

My linux is (uname -a)
Linux camoc0002 2.6.16.53-0.16-smp #1 SMP Tue Oct 2 16:57:49 UTC 2007
i686 i686 i386 GNU/Linux

Again, here is the output.
Could it be related to my printf library?
