If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.

(Please choose at least one native build and, if supported, at least one cross build. More are better.)

    Revbumping most dependants after this will be necessary, because there
    is a very visible bug where "<program> --usage" or "<program> --help"
    segfaults.

    Forking and switching upstream has been done because the project isn't
    active and no one has forked it themselves yet, at least that I could
    find.
