> On some environments used for automation, all the tests run with code coverage enabled but the report at the end is empty. Impala is generating the necessary gcno/gcda files on exit, so this seems to be a bug during report generation in that environment. It works fine locally on my Ubuntu 20 development box, so there is something special about the environment.
> Testing with the latest version of gcovr (7.2) doesn't show the same issue, so one path to fixing this is to upgrade to gcovr==7.2. gcovr 7.2 requires python 3.8, so it would involve switching to the toolchain 3.8 python rather than the 3.7 python.
