    Can you please add your GDB version? The version parsing is done with regex r"^GNU gdb.*?\b(\d+).(\d+)" and I think it's not matching your version which seems to be empty. Adding the output of gdb -nx --version will be helpful in debugging this since the output is the string used against the regex.

    Thanks

    I believe that this issue is a duplicated of bpo-40436 which was fixed by:

    commit ec9bea4
    Author: Victor Stinner <vstinner@python.org>
    Date: Wed Apr 29 17:11:48 2020 +0200

    bpo-40436: Fix code parsing gdb version (GH-19792)

test_gdb and test.pythoninfo now check gdb command exit code.

    If it's not the case, please provide more information, as requested.
