Ubuntu 21.04 has the option of the gcc-11 compiler suite.
Although not ready for production use on C++ code*,
it includes a static analyzer with the option '-fanalyzer'.
Out of curiosity I tried using this option when building the geotiff
driver for 3.3.0; command line and output attempting to build cogdriver.lo
available at
https://www.aitchison.me.uk/GDAL/make.cogdriver.errlog.gcc-fanalyzer.20210515
(terminal colour escape codes may be mangled).
Sadly my C++ isn't up to figuring out whether the analyzer is finding
bugs in the code or the code is finding bugs in the analyzer.
