Hello all, CMake upstream here. After upgrading to clang 6 scan-build, we're seeing a rather odd warning in our in-source libuv build. It's complaining about "Assigned value is garbage or undefined" after calling open() and comparing it to "== -1" rather than "< 0", but only in this one particular call.
You can see the warning at https://open.cdash.org/viewBuildError.php?ty pe=1&buildid=5707465 . This warning also appears when building libuv on its own. I've opened a PR on libuv upstream ( https://github.com/libuv/libuv/pul l/2140 ) which fixes the warning, but what I don't understand is why this is the only place where this appears - there are lots of other places where open() is called and compared against -1, but they don't trigger the warning. I also have not been able to come up with a minimal reproducible example. Anyone have any insight as to why this might be happening?
