    There seems to be a memory leak in bash when a local array is declared within a function.     I also tested this on "GNU bash, version 5.0.17(1)-release (x86_64-redhat-linux-gnu)" and that one works without any leaks.

     leak() { local arr=("leak"); }
     while :; do leak; done

Thanks for the report. This was fixed back in January as the result of
