Hi,
I think I found my problem. Both Valgrind-3.7.0-SVN and
Valgrind-3.6.0 works well for syscall 330 and the dup3 program on my
platform. It was Valgrind-3.5.0 which causes the problem. Here is the
story of this problem:
Valgrind-3.5.0 was distributed with Fedora12, so I installed the
software in /usr/bin when the Operating System was installed. Latter,
I installed the new version(3.7.0) in /usr/local/valgrind, I just add
the location to the user's $PATH envrionment so that I could find the
command easily. The problem is when I use the command "sudo valgrind
...", it switch the current user to the root, and the environment
variables change. So each time when I typed "valgrind --version",
which prints "valgrind-3.7.0", I thought I was using the new version.
However, when I add "sudo" in the front, I switched to the old version
again.
Thanks for your help.
