Description Jesper Schmitz Mouridsen freebsd_committer freebsd_triage 2019-10-26 17:56:00 UTC 
Follow up on bug #237662 the root cause was in mesa, it reused the actual locale
and not the C locale as intended in mesa-18.3.2/src/util/strtod.c  

if you define _GNU_SOURCE in that file strtof_l gets called as intended, i.e with the C locale loc thus not scrambling numbers as 0.444  with a decimal sep of "," from the users locale...

Hi!
Can you try the attached patch?
Apply it against the ports tree, then rebuild and reinstall mesa-dri and mesa-libs.

  graphics/mesa: Add -D_GNU_SOURCE to compile flags

  Add -D_GNU_SOURCE to compile flags when building on FreeBSD.  This is needed
