There's a similar bug on VS at https://developercommunity.visualstudio.com/t/c-intellisense-find-all-references-confirms-refere/1014321, but the difference is that VS is differentiating between the references that are local to the function and global, e.g. a simpler repro with one file is:

int test;
int func(int test){}

Is this bug on VS then?

No. I may have a fix soon...
