Hasso Tepper has a “BIG FAT WARNING” about two new issues: threaded programs are broken on bleeding-edge DragonFly because of a possible GCC bug that was only recently exposed, and Xorg in pkgsrc has issues with the Intel driver.
Simon ‘corecode’ Schubert already has one change in that may fix the issue with threaded programs, and is working on the Intel driver issue.
Update: more threading changes.
At the risk of stating the obvious — from reading Phoronix etc., I gather the Intel drivers have become a headache for everyone in *NIX-land, so at least the BSDs aren’t suffering alone here.
