The analyzer found a potential error: the function receives a very odd value as an actual argument.
Consider the sample:
bool Matrix4::operator==(const Matrix4& other) const {
if (memcmp(this, &other, sizeof(Matrix4) == 0))
return true;
...We deal with a misprint here: one round bracket is in a wrong place. Unfortunately, this error is not clearly visible and might exist in the code for a long time. Because of this misprint the size of memory being compared is calculated with the "sizeof(Matrix4) == 0" expression. Since the result of the expression is 'false', 0 bytes of memory are compared. This is the fixed code:
bool Matrix4::operator==(const Matrix4& other) const {
if (memcmp(this, &other, sizeof(Matrix4)) == 0)
return true;
...
