TOUCHE: Code analysis warnings

Reported by: Templier Owned by: bluegr
Priority: normal Component: Engine: Touche
Keywords: build Cc:


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\touche\resource.cpp(477): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'spr->ptr', which is passed as an argument to 'realloc', will cause the original memory block to be leaked
d:\sources\scummvm\scummvm\engines\touche\touche.cpp(2363): warning C6201: Index '40' is out of valid index range '0' to '39' for possibly stack allocated buffer '_conversationChoicesTable'
d:\sources\scummvm\scummvm\engines\touche\touche.cpp(2364): warning C6201: Index '40' is out of valid index range '0' to '39' for possibly stack allocated buffer '_conversationChoicesTable'

The last two look like false positives.

If you want to try it yourself, you will need:
- the create_project patch set, along with the WIP code analysis patch (
- the following patch to silence some false positives ( )

- Visual Studio 2010 Ultimate or Team System (create_project support for analysis with VS2005/2008 isn't complete yet)

All three are false positives. There is a check for realloc() for the first one, which terminates with error(). The other two are false positives, the loop they refer to is fine

Closing as invalid
