Updated Clang static analysis results / Valgrind update

[Austin English]

Web space usage was getting a bit high, so I've uploaded a tarball to
a file download service:
http://www.sendspace.com/file/5hot36

austin@aw21 ~ $ sha1sum scan-build-2011-07-02.tar.bz2
ac3cb3920ef97641fff1f5376f8136cef01f15bf  scan-build-2011-07-02.tar.bz2

to use, just extract and open in your favorite browser:
$ firefox index.html

this was run against Clang from svn: clang version 3.0 (trunk 134320)

Please send me any false positives that you'd like me to report upstream.

Cheers,
Austin

P.S. For those of you wanting Valgrind results, I'm currently hitting
a nasty Valgrind bug, waiting on upstream to fix:
https://bugs.kde.org/show_bug.cgi?id=275673

(Thanks to Andrew N for finding the faulty commit)

FWIW, you could use xz instead of bzip2 to further reduce the download
size (54 MiB)
I got the size down to 46 MiB using default settings, and 25 MiB using
max compression (xz -9)

Updated clang results, with:
clang version 3.0 (trunk 135936) and wine-1.3.25-52-g9d7d37f

are at http://www.sendspace.com/file/x81pne
77f1b2d0fdd8cb79d4caf20279b36dc047fcc325  scan-build-2011-07-25.tar.xz

This gives 1815 warnings (previously had 1857). Again, if you see any
false positives, please let me know so that I can report them
upstream.

For valgrind, see http://austinenglish.com/logs/valgrind/2011-07-25-10.19
I've disabled a few tests, to workaround valgrind bug 275673. See
http://code.google.com/p/winezeug/source/diff?spec=svn2431&r=2431&fo...

I've got some more interesting stuff in the works, time permitting.
Keep tuned ;-).

Cheers,
Austin

in your actual valgrind logs there is quite much noise about
at  ??? (in /usr/lib/i386-linux-gnu/libfontconfig.so.1.4.4)
what's that?

Thanks for letting me know. I filed:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635609
for that.

I've added a suppression for it, today's results are fontconfig free:

we're down to 1629 from 1815 (though some of that could be improved
Clang analyzer) :).

Thanks for posting it, it is really helpful. I managed to find and fix
a double free in one of my tests.

Keep it up,
