PVS-Studio Messages

What bugs can PVS-Studio detect?

We grouped the diagnostic, so that you can get the general idea of what PVS-Studio is capable of.

As it is hard to do strict grouping, some diagnostics belong to several groups. For example, the incorrect condition "if (abc == abc)" can be interpreted both as a simple typo, but also as a security issue, because it leads to the program vulnerability if the input data are incorrect.

Some of the errors, on the contrary, couldn't fit any of the groups, because they were too specific. Nevertheless this table gives the insight about the functionality of the static code analyzer.
