Description
Here are the warnings I get when compiling 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\graphics\font.cpp(232): warning C6054: String 'facename' might not be zero-terminated d:\sources\scummvm\scummvm\graphics\font.cpp(240): warning C6054: String 'copyright' might not be zero-terminated d:\sources\scummvm\scummvm\graphics\font.cpp(509): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'pf->bits', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\graphics\scaler.cpp(101): warning C6011: Dereferencing NULL pointer 'RGBtoYUV' d:\sources\scummvm\scummvm\graphics\video\codecs\qdm2.cpp(1359): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'vlc->table', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\graphics\video\codecs\qdm2.cpp(3115): warning C6288: Incorrect operator: mutual inclusion over && is always zero. Did you intend to use || instead? d:\sources\scummvm\scummvm\graphics\video\coktel_decoder.cpp(2309): warning C6011: Dereferencing NULL pointer 'out++' d:\sources\scummvm\scummvm\graphics\video\coktel_decoder.cpp(2470): warning C6001: Using uninitialized memory 'data' d:\sources\scummvm\scummvm\graphics\video\mpeg_player.cpp(369): warning C6011: Dereferencing NULL pointer '_rgbToPix' d:\sources\scummvm\scummvm\graphics\video\mpeg_player.cpp(390): warning C6011: Dereferencing NULL pointer 'r_2_pix_alloc' d:\sources\scummvm\scummvm\graphics\video\mpeg_player.cpp(362): warning C6011: Dereferencing NULL pointer '_colorTab' d:\sources\scummvm\scummvm\graphics\video\mpeg_player.cpp(382): warning C6011: Dereferencing NULL pointer 'Cr_r_tab'
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) - 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)

font.cpp: warnings fixed, and appropriate comments added scaler.cpp: false positive, RGBtoYUV is always initialized above qdm2.cpp: warnings already fixed coktel_decoder.cpp: warnings already fixed mpeg_player.cpp: the warnings all look like false positives
