[cfe-dev] RFC clang analyzer false positives (for loop)

[Daniel Marjamäki via cfe-dev]

Hello!

As far as I know, having few false positives is a major goal for the Clang static analyzer.

Yes I understand that false positives are inevitable. So a few fixes in my code to hide them are expected.

However if most warnings for a particular use case are in practice false positives I say these should be dropped. So I think the question should be if most warnings are false positives? Do you think your true positive ratio in your own code is good? Is it higher than 50%?

> But the example you have given is *not* wrong. It is completely correct.

Imho it is a false positive if I can easily see with human intelligence that the warning is wrong.

Best regards,
Daniel Marjamäki
