V763. Parameter is always rewritten in function body before being used.
The analyzer detected a potential error in the body of a function: one of the function parameters is overwritten before being used, which results in losing the value passed to the function.
Consider the following example:
void Foo(Node A, Node B)
{
A = SkipParenthesize(A);
B = SkipParenthesize(A); // <=
AnalyzeNode(A);
AnalyzeNode(B);
}The 'A' and 'B' parameters are mixed up because of a typo, which leads to assigning a wrong value to the 'B' variable. The fixed code should look like this:
void Foo(Node A, Node B)
{
A = SkipParenthesize(A);
B = SkipParenthesize(B);
AnalyzeNode(A);
AnalyzeNode(B);
