When I try to run the checks in parallel, with the following command:

cppcheck --project=build/compile_commands.json --enable=all -j4 --addon=misra.json --xml-version=2

the report is littered with errors such as this one:

                <error id="internalError" severity="information"

column="0"/>

No such errors are reported if I remove the -j4 arg, or the
--addon=misra.json arg.

I'd like to be able to check files in parallel because it's pretty
time-consuming like this.
