false positive report
Hello.
I'm using scan-build-11 from clang-tools-11 1:11.0.1-2~bpo10+1 (Debian 10).
Attaching the false positive report.
Line 1519: Checking that bleft > 0.
Line 1524: Checking that bleft <= 7.
Line 1527: 1 << (32 - bleft)
scan-build reports that (32 - bleft) is negative. But it cannot be negative,
because bleft=[1..7].
Best regards, Vladimir</pre>
