Bug#906027: shellcheck: unable to decommit memory: Invalid argument

[Luke Goodsell]

Package: shellcheck
Version: 0.4.4-4

In Debian 9, running shellcheck against a moderate-size file results in the error message

    shellcheck: unable to decommit memory: Invalid argument

I can reproduce this with these commands:

    docker run -it debian:9
    apt-get -y update
    apt-get -y install shellcheck
    echo '#!/bin/bash' > test.sh; for i in $(seq 1000); do echo 'echo "hi"' >> test.sh; done
    shellcheck test.sh
    # shellcheck: unable to decommit memory: Invalid argument
    # shellcheck: unable to decommit memory: Invalid argument
    # shellcheck: unable to decommit memory: Invalid argument

Since shellcheck is used in CI tests and produces no output on success, these error messages shouldn't be present.
