Abstratc. The id Software company possesses a PVS-Studio license. However, we decided to test the source codes of Doom 3 that have been recently laid out on the Internet. The result is the following: we managed to find just few errors, but still they are there. I think it can be explained by the following fact.
A part of the Doom 3 code is still in use, and perhaps developers have fixed errors there. And another part of the code is obsolete and not used now. Most likely, the suspicious code fragments have been found in this very part.
For those who want to know more on the subject, in this article we cite code fragments the PVS-Studio analyzer gave warnings for. As usually, let me remind you that I will speak only on some of the warnings, while the other project fragments require us to know the program’s structure, so I did not examine them.
