Build issue with lib/vcsn/dot/parse.cc on archlinux
Build of %2.8 on archlinux fails with compilation error of
This problem happens in pipeline archlinux jobs and not debian (see recent pipeline run https://gitlab.lrde.epita.fr/vcsn/vcsn/pipelines/11749). I also reproduce it locally on my archlinux on commit c71e8f7d (current master and %2.8) but not using the AUR package which compiles from the release tarball of 2.8.
parse.cc seems to be generated from parse.yy with bison during the build process, recent archlinux environment seem to result in a botched generation of the file. The release tarball is distributed with the file already generated, hence the absence of that build failure using the AUR package.
Maybe bison introduced a behavior difference in a version between debian's and archlinux's that break vcsn build, I'll try to look into it.
