Impact-Medium
Affected rules
A1-1-2
Description
This rule looks for compilations with no warning flags. However, it will falsely detect
-Wno-*
flags as if they are warning flags.Notably, gcc is often built with
-Wformat
enabled by default. This can be suppressed with-Wno-format
, which would cause the false negative.Note the same issue exists with
-w
which suppresses all-W*
flags, which is failing linux/gcc tests, and I created #688 to fix. However, this issue is, philosophically, one step further yet than that PR in terms of altering current behavior.Example
