Description
Here are the warnings I get when compiling the engine using Code Analysis in VS2010. I tried to remove all the obvious false positives. Some warnings look suspicious, others are pointing to correct code that still might benefit from better error checking.
d:\sources\scummvm\scummvm\engines\gob\draw.cpp(331): warning C6011: Dereferencing NULL pointer 'coord2' d:\sources\scummvm\scummvm\engines\gob\draw_playtoons.cpp(154): warning C6259: Labeled code is unreachable: '(<expression> & 0xff)' in a switch-expr cannot evaluate to '0xffffffffffffffff' d:\sources\scummvm\scummvm\engines\gob\game.cpp(360): warning C6202: Buffer overrun for '_curTotFile', which is possibly stack allocated, in call to 'strcpy': length '20' exceeds buffer size '14' d:\sources\scummvm\scummvm\engines\gob\game.cpp(373): warning C6202: Buffer overrun for '_curTotFile', which is possibly stack allocated, in call to 'strcpy': length '20' exceeds buffer size '14' d:\sources\scummvm\scummvm\engines\gob\game.cpp(338): warning C6001: Using uninitialized memory '_captureCounter' d:\sources\scummvm\scummvm\engines\gob\game.cpp(322): warning C6011: Dereferencing NULL pointer '_vm->_inter->_variables' d:\sources\scummvm\scummvm\engines\gob\sound\adlib.cpp(243): warning C6323: Use of arithmetic operator on Boolean type(s)
Note: If you want to try it yourself, you will need: - the create_project patch set, along with the WIP code analysis patch (http://bitbucket.org/Littleboy/scummvm-jt/src/942f13a9f24b ) - the following patch to silence some false positives ( http://bitbucket.org/Littleboy/scummvm-jt/src/tip/COMMON%20-%20Add%20annotations%20for%20analysis%20build%20configuration.patch ) - Visual Studio 2010 Ultimate or Team System (create_project support for analysis with VS2005/2008 isn't complete yet)

I'm still getting the _captureCounter one.
You can silence it easily by initializing _captureCounter to 0 at the beginning.

Here are the results of the latest analysis build:
d:\sources\scummvm\scummvm-jt\engines\gob\save\savefile.cpp(339): warning C4805: '!=' : unsafe mix of type 'byte' and type 'bool' in operation

Fixed. Thanks for reporting :)
I'll leave the comments open, so you can yell if there's more :P
