Comment (by machielbos):

 Same problem here. Updated to darwin19, tried to reinstall all ports and
 atlas build fails with

 :info:build cd bin/ ; ./xatlas_build -1 0 -a 1 -l 1
 :info:build /bin/sh: line 1: 29260 Segmentation fault: 11  ./xatlas_build
 -1 0 -a 1 -l 1
 :info:build make[1]: *** [build] Error 139
