Version:           valgrind-3.0.1 (using KDE KDE 3.3.0)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc (GCC) 4.0.2 20050821 (prerelease) (Debian 4.0.1-6) i didn't compile valgrind itself (=debian unstable package) , just the program i want to check with valgrind.
OS:                Linux

I'm having some troubles with Valgrind and the code of
the recently started game OpenAnno [1].

I already searched the FAQ and the mailing list for an
answer to this, but i didn't find anything that seems
to be related to my problem.

I posted in the mailing list and was being told to file
it here, so i did. (i also added an entry in the sourceforge bug-tracker [2], but it seems to be unused)

I attached the error below, if you need more info i
will try to provide it.

This output is what i get when i run
# valgrind -v --tool=none ./openanno
(It really doesn't depend on the tool i use, the error
is displayed anyway)
