V3091. Empirical analysis. It is possible that a typo is present inside the string literal. The 'foo' word is suspicious.

When the analyzer detects two identical string literals, it tries to figure out if they result from misuse of Copy-Paste. Be warned that this diagnostic is based on an empirical algorithm and may sometimes generate strange false positives.

Consider the following example:

string left_str = "Direction: left.";
string right_str = "Direction: right.";
string up_str = "Direction: up.";
string down_str = "Direction: up.";

This code was written using the Copy-Paste technique. At the end, the programmer forgot to change the string literal from "up" to "down". The analyzer treats this code as incorrect and points out the suspicious word "up" in the last line.

Fixed code:

string left_str = "Direction: left.";
string right_str = "Direction: right.";
string up_str = "Direction: up.";
string down_str = "Direction: down.";

You can look at examples of errors detected by the V3091 diagnostic.
