The analyzer has detected a possible error that has to do with meaningless variable assignments.
Consider this example:
int a, b, c; ... a = b; c = 10; b = a;
The "B = A" assignment statement in this code does not make sense. It might be a typo or just unnecessary operation. This is what the correct version of the code should look like:
a = b; c = 10; b = a_2;
You can look at examples of errors detected by the V3037 diagnostic.
