[gdal-dev] gnu g++ v11 -fanalyzer - possibly NULL operator new

[Andrew C Aitchison]

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.
