The analyzer has detected a potential error that may occur when calling the 'swap' function. The function receives identical actual arguments, which is very strange. The programmer must have made a misprint.
Have a look at this example:
int arg1, arg2;
....
swap(arg1, arg1);
....A misprint causes the swap() function to swap the value of the 'arg1' variable for itself. The code should be fixed in the following way:
swap(arg1, arg2);The following sample is also considered suspicious:
MyClass arg1, arg2;
....
arg1.Swap(arg1);
....It can be fixed in the following way:
arg1.Swap(arg2);This diagnostic is classified as:
