-------------------------------
same culprit glib2-2.68.0, downgrading solves the problem.

Maybe I'll suggest Samuel to tag 0.10.3, as there has been a lot of changes since 25 November 2020 in the tree. I will build from git master first, but usually there's no regression.

that solves the speech-distacher build (modify SlackBuild)

fixed in -current tree.
