Description of problem:

from build [2] we got a strange koji error [3] after check i686 build and armv7 not generate the same doc files using texlive , comparing last good build of gdal (2018-02-13) I found the Segmentation fault, I tried another gdal scratch build some minutes ago and still have the same problem [4]
